  • pointPolygonTest in OpenCV 2.2

    - by Mathieu Dubois
    I wanted to use pointPolygonTest but I have a problem. I'm stuck to OpenCV2.2. I tried to use the code found here: http://docs.opencv.org/doc/tutorials/imgproc/shapedescriptors/point_polygon_test/point_polygon_test.html#point-polygon-test I use findContours to detect contours in an image. Under OpenCV 2.2 returns a vector< vector<Point> >. The problem is that pointPolygonTest accept a matrix as an entry. Therefore the code doesn't compile with OpenCV 2.2: erreur: invalid initialization of reference of type ‘const cv::Mat&’ from expression of type ‘std::vector<cv::Point_<int>, std::allocator<cv::Point_<int> > >’ Under more recent OpenCV versions, the findContours function returns vector<Mat> so it's easy to pass to pointPolygonTest (see the example). I guess I could convert the vector< vector<Point> > to vector<Mat>. Unfortunately the documentation is not very clear about the format. Does anybody have an advice?

  • What is the equivalent of Application.ProcessMessages, Application.Handle and Application.Terminated

    - by DavidB
    Hi, I am new to Writing Windows Service apps and having problems. Written in Delphi, I have written a normal windows application to check and debug the major parts of the code and now have to convert it to an NT Service. My code has to launch a windows application which I do using the following code. function Run_Program : boolean; var SEInfo : TShellExecuteInfo; ExitCode : DWORD; begin Result := false; FillChar(SEInfo, SizeOf(SEInfo),0); SEInfo.cbSize :=SizeOf(TShellExecuteInfo); With SEInfo do begin fMask := SEE_MASK_NOCLOSEPROCESS; Wnd := **Application.Handle**; lpFile := PChar(Exe_Prog); lpParameters := PChar(Exe_Param); nShow := SW_SHOWNORMAL; end; If ShellExecuteEx(@SEInfo) then begin repeat Application.ProcessMessages; GetExitCodeProcess(SEInfo.hProcess, ExitCode); until (ExitCode <> STILL_ACTIVE) OR Application.Terminated OR NOT q1.fieldbyName('Delay').AsBoolean; If ExitCode <> STILL_ACTIVE then Record_Event(Exe_Prog + ' completed ') else Record_Event(Exe_Prog + ' activated '); Result := true; end else Record_Event('Error Starting '+ Exe_Prog+ ' '); end; When this is put in the service app the compiler fails with 3 errors: Undeclared identifiers.. 1) Handle 2) ProcessMessages and 3) Terminated. My question is.. are there equivalent procedures that can be used in a service application or should I approach the problem differently in a service application? Any help would be appreciated

  • JSON and jQuery.ajax

    - by Andreas
    Hello, im trying to use the jQuery UI autocomplete to communitate with a webservice with responseformate JSON, but i am unable to do so. My webservice is not even executed, the path should be correct since the error message does not complain about this. What strikes me is the headers, response is soap but request is json, is it supposed to be like this? Response Headersvisa källkod Content-Type application/soap+xml; charset=utf-8 Request Headersvisa källkod Accept application/json, text/javascript, */* Content-Type application/json; charset=utf-8 The error message i get is as follows (sorry for the huge message, but it might be of importance): soap:ReceiverSystem.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Xml.XmlException: Data at the root level is invalid.

  • Android - drawing path as overlay on MapView

    - by Rabas
    Hello, I have a class that extends Overlay and implemments Overlay.Snappable. I have overriden its draw method: @Override public void draw(Canvas canvas, MapView mv, boolean shadow) { Projection projection = mv.getProjection(); ArrayList<GeoPoint> geoPoints = new ArrayList<GeoPoint>(); //Creating geopoints - ommited for readability Path p = new Path(); for (int i = 0; i < geoPoints.size(); i++) { if (i == geoPoints.size() - 1) { break; } Point from = new Point(); Point to = new Point(); projection.toPixels(geoPoints.get(i), from); projection.toPixels(geoPoints.get(i + 1), to); p.moveTo(from.x, from.y); p.lineTo(to.x, to.y); } Paint mPaint = new Paint(); mPaint.setStyle(Style.FILL); mPaint.setColor(0xFFFF0000); mPaint.setAntiAlias(true); canvas.drawPath(p, mPaint); super.draw(canvas, mv, shadow); } As you can see, I make a list of points on a map and I want them to form a polygonal shape. Now, the problem is that when I set paint style to be FILL or FILL_AND_STROKE nothing shows up on the screen, but when I set it to be just stroke, and set stroke width, it acctually draws what it is supposed to draw. Now, I looked for solution, but nothing comes up. Can you tell me if I something missed to set in the code itself, or are there some sorts of constraints when drawing on Overlay canvases? Thanks

  • VB .NET DirectCast and Type Reflection

    - by msarchet
    The application that I am working on has a generic Parent Form called RSChild, that is used to perform some operations depending on whether or not the control that is contained within it is in a MdiTabManager or inside of its own modal form. Then the actual User Controls contained within Inherit from a Interface Called ObjectEdit (Objects that we allow to be edited). At a point in my code I am doing this. Public Function doesTabExist(ByVal id As Integer, ByVal recordType As Enums.eRecordType) As Boolean Dim alikePages As Object = (From tabs In DirectCast(Control.FromHandle(MainForm.SharedHandle), MainForm).XtraTabbedMdiManager1.Pages Where DirectCast(tabs.MdiChild, RSChild).RSObject.RecordType = recordType Select tabs) For Each page As DevExpress.XtraTabbedMdi.XtraMdiTabPage In alikePages Select Case recordType Case Enums.eRecordType.Doctor If id = DirectCast(castTabPageToRSChild(page).RSObject, UI.Doctor).ID Then pageToActive(page) Return True End If 'rest of the cases so the case block is repeated 10 times' End Function And my castTabPageToRSChild(page) is a lambda function as Such Dim castTabPageToRSChild As Func(Of DevExpress.XtraTabbedMdi.XtraMdiTabPage, RSChild) = Function(page) DirectCast(page.MdiChild, RSChild) So my Question is, I have about 10 case statements, all because I can't seem to find a way to use reflection to get the underlying Type of the RSObject Object. So I have the whole If block repeated over and over. I tried doing castTabPageToRSChild(page)RSObject.GetType and using that in the DirectCast and I also tried creating another object that was separate from that and doing the same thing. My code works as intended I'm just trying to see if there is a manner in which I didn't have a lot of replicated code. My vision would be to do something like For Each page As XtraMdiTabPage In alikePages If id = DirectCast(castTabPageToRSchild(page).RSObject, TypeOfThatObject).Id Then Return True Next However I have a feeling this is not possible due to the behavior of DirectCast.

  • Spring 3 DI using generic DAO interface

    - by Peders
    I'm trying to use @Autowired annotation with my generic Dao interface like this: public interface DaoContainer<E extends DomainObject> { public int numberOfItems(); // Other methods omitted for brevity } I use this interface in my Controller in following fashion: @Configurable public class HelloWorld { @Autowired private DaoContainer<Notification> notificationContainer; @Autowired private DaoContainer<User> userContainer; // Implementation omitted for brevity } I've configured my application context with following configuration <context:spring-configured /> <context:component-scan base-package="com.organization.sample"> <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation" /> </context:component-scan> <tx:annotation-driven /> This works only partially, since Spring creates and injects only one instance of my DaoContainer, namely DaoContainer. In other words, if I ask userContainer.numberOfItems(); I get the number of notificationContainer.numberOfItems() I've tried to use strongly typed interfaces to mark the correct implementation like this: public interface NotificationContainer extends DaoContainer<Notification> { } public interface UserContainer extends DaoContainer<User> { } And then used these interfaces like this: @Configurable public class HelloWorld { @Autowired private NotificationContainer notificationContainer; @Autowired private UserContainer userContainer; // Implementation omitted... } Sadly this fails to BeanCreationException: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.organization.sample.dao.NotificationContainer com.organization.sample.HelloWorld.notificationContainer; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.organization.sample.NotificationContainer] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} Now, I'm a little confused how should I proceed or is using multiple Dao's even possible. Any help would be greatly appreciated :)

  • Java - Trying to log into website with invalid ssl certificate using httpclient

    I'm trying to log into site with invalid ssl certificate and I have the following code.

  • Delphi: How to respond to WM_SettingChange/WM_WinIniChange?

    - by Ian Boyd
    i need to know when my application recieves a WM_SETTINGCHANGE message (formerly known as WM_WININICHANGE). Problem is that the message pump in TApplication sends it down a black hole (default handler) before i can get a chance to see it: procedure TApplication.WndProc(var Message: TMessage); ... begin Message.Result := 0; for I := 0 to FWindowHooks.Count - 1 do if TWindowHook(FWindowHooks[I]^)(Message) then Exit; CheckIniChange(Message); with Message do case Msg of WM_SETTINGCHANGE: begin Mouse.SettingChanged(wParam); Default; <----------------------*poof* down the sink hole end; ... end; ... end; The procedure CheckIniChange() doesn't throw any event i can handle, neither does Mouse.SettingChanged(). And once the code path reaches Default, it is sent down the DefWindowProc drain hole, never to be seen again (since the first thing the WndProc does is set the Message.Result to zero. i was hoping to assign a handler to a TApplicationEvents.OnMessage event: procedure TdmGlobal.ApplicationEvents1Message(var Msg: tagMSG; var Handled: Boolean); begin case Msg.message of WM_SETTINGCHANGE: begin // Code end; end; end; But the OnMessage event is only thrown for messages that come through the message pump. Since the WM_SETTINGCHANGE message is "handled", it never sees the PeekMessage TranslateMessage DispatchMessage system. How can i respond to the windows broadcast WM_SETTINGCHANGE?

  • Overlay only draws line between first 2 GPS points in Android

    - by LordSnoutimus
    Hi, I am experiencing an unusual error using ItemizedOverlay in Android. I am creating a GPS tracking device that plots a route between waypoints stored in a database. When I provide the first two sets of longitude and latitude points through the emulator in Eclipse, it draws a red line just how I want it, but if I send another GPS point, it animates to the point, but does not draw a line from the last point. public class MyOverlay extends ItemizedOverlay { // private Projection projection; private Paint linePaint; private Vector points; public MyOverlay(Drawable defaultMarker) { super(defaultMarker); points = new Vector<GeoPoint>(); //set colour, stroke width etc. linePaint = new Paint(); linePaint.setARGB(255, 255, 0, 0); linePaint.setStrokeWidth(3); linePaint.setDither(true); linePaint.setStyle(Style.FILL); linePaint.setAntiAlias(true); linePaint.setStrokeJoin(Paint.Join.ROUND); linePaint.setStrokeCap(Paint.Cap.ROUND); } public void addPoint(GeoPoint point) { points.addElement(point); } public void draw(Canvas canvas, MapView view, boolean shadow) { int size = points.size(); Point lastPoint = new Point(); if(size == 0) return; view.getProjection().toPixels(points.get(0), lastPoint); Point point = new Point(); for(int i = 1; i<size; i++){ view.getProjection().toPixels(points.get(i), point); canvas.drawLine(lastPoint.x, lastPoint.y, point.x, point.y, linePaint); lastPoint = point; } } @Override protected OverlayItem createItem(int arg0) { // TODO Auto-generated method stub return null; } @Override public int size() { // TODO Auto-generated method stub return 0; } }

  • Integrating PartCover.NET with NAnt

    - by davandries
    Hello, I'm trying to integrate PartCover.NET with NAnt and CruiseControl.NET I can run PartCover.NET browser without problems, but it does not work once I try to run it in an NAnt task (in my CCNET build). There must be an issue with my NAnt target but I can't find it. Maybe someone had experienced the same issues in the past?. <target name="CoverageUnitTest" description="Code coverage of unit tests"> <exec program="${PartCover.exe}"> <arg value="--target=${NUnit.console}" /> <arg value="--target-work-dir=${project.dir}\bin\${configuration}"/> <arg value="--target-args=${project}.dll" /> <arg value="--output=C:\partcover.xml" /> <arg value="--include=[*]*" /> </exec> </target> In CruiseControl, I got the following error message: [exec] Invalid option '--target C:\NUnit\bin\nunit-console.exe' Build Error: NAnt.Core.BuildException External Program Failed: C:\PartCover\PartCover.exe (return code was -1) in C:\default.build line: 20 col: 4 at NAnt.Core.Tasks.ExternalProgramBase.ExecuteTask() at NAnt.Core.Tasks.ExecTask.ExecuteTask() at NAnt.Core.Task.Execute() at NAnt.Core.Target.Execute() at NAnt.Core.Project.Execute(String targetName, Boolean forceDependencies) at NAnt.Core.Project.Execute() at NAnt.Core.Project.Run() thanks !

  • What do you mean by the expressiveness in a programming language?

    - by prosseek
    I see a lot of the word 'expressiveness' when people want to stress one language is better than the other. But I don't see exactly what they mean by it. Is it the verboseness/succinctness? I mean, if one language can write down something shorter than the other, does that mean expressiveness? Please refer to my other question - http://stackoverflow.com/questions/2411772/article-about-code-density-as-a-measure-of-programming-language-power Is it the power of the language? Paul Graham says that one language is more powerful than the other language in a sense that one language can do that the other language can't do (for example, LISP can do something with macro that the other language can't do). Is it just something that makes life easier? Regular expression can be one of the examples. Is it a different way of solving the same problem: something like SQL to solve the search problem? What do you think about the expressiveness of a programming language? Can you show the expressiveness using some code? What's the relationship with the expressiveness and DSL? Do people come up with DSL to get the expressiveness?

  • WCF/MSMQ Transport Security with Certificates

    - by user104295
    Hi there, my goal is to secure the communication between MSMQ Queue Managers – I don’t want unknown clients sending messages to my MSMQ server. I have spent many hours now trying to get Transport security working for the net.msmq binding in WCF, where MSMQ is in Workgroup mode and the client and server do not have Active Directory… so I’m using certificates. I have created a new X.509 certificate, called Kristan and put it into the “Trusted people” store on the server and into the My store of Current User of the client. The error I’m getting is: An error occurred while sending to the queue: Unrecognized error -1072824272 (0xc00e0030).Ensure that MSMQ is installed and running. If you are sending to a local queue, ensure the queue exists with the required access mode and authorization. Using smartsniff, I see that there’s no attempted connection with the remote MSMQ, however, it’s an error probably coming from the local queue manager. The stack trace is: at System.ServiceModel.Channels.MsmqOutputChannel.OnSend(Message message, TimeSpan timeout) at System.ServiceModel.Channels.OutputChannel.Send(Message message, TimeSpan timeout) at System.ServiceModel.Dispatcher.OutputChannelBinder.Send(Message message, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation) at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message) The code:- EndpointAddress endpointAddress = new EndpointAddress(new Uri(endPointAddress)); NetMsmqBinding clientBinding = new NetMsmqBinding(); clientBinding.Security.Mode = NetMsmqSecurityMode.Transport; clientBinding.Security.Transport.MsmqAuthenticationMode = MsmqAuthenticationMode.Certificate; clientBinding.Security.Transport.MsmqProtectionLevel = System.Net.Security.ProtectionLevel.Sign; clientBinding.ExactlyOnce = false; clientBinding.UseActiveDirectory = false; // start new var channelFactory = new ChannelFactory<IAsyncImportApi>(clientBinding, endpointAddress); channelFactory.Credentials.ClientCertificate.SetCertificate("CN=Kristan", StoreLocation.CurrentUser, StoreName.My); The queue is flagged as ‘Authenticated’ on the server. I have checked the effect of this and if I turn off all security in the client send, then I get ‘Signature is invalid’ – which is understandable and shows that it’s definitely looking for a sig. Are there are special ports that I need to check are open for cert-based msmq auth? thanks Kris

  • CKEditor instance already exists

    - by jackboberg
    I am using jquery dialogs to present forms (fetched via AJAX). On some forms I am using a CKEditor for the textareas. The editor displays fine on the first load. When the user cancels the dialog, I am removing the contents so that they are loaded fresh on a later request. The issue is, once the dialog is reloaded, the CKEditor claims the editor already exists. uncaught exception: [CKEDITOR.editor] The instance "textarea_name" already exists. The API includes a method for destroying existing editors, and I have seen people claiming this is a solution: if (CKEDITOR.instances['textarea_name']) { CKEDITOR.instances['textarea_name'].destroy(); } CKEDITOR.replace('textarea_name'); This is not working for me, as I receive a new error instead: TypeError: Result of expression 'i.contentWindow' [null] is not an object. This error seems to occur on the "destroy()" rather than the "replace()". Has anyone experienced this and found a different solution? Is is possible to 're-render' the existing editor, rather than destroying and replacing it? UPDATED Here is another question dealing with the same problem, but he has provided a downloadable test case.

My behavior is this: using System.Windows.Controls; using System.Windows; using System.Windows.Controls.Primitives; namespace AttachedBehaviours { public class ConfirmChangeBehaviour { public static bool GetConfirmChange(Selector cmb) { return (bool)cmb.GetValue(ConfirmChangeProperty); } public static void SetConfirmChange(Selector cmb, bool value) { cmb.SetValue(ConfirmChangeProperty, value); } public static readonly DependencyProperty ConfirmChangeProperty = DependencyProperty.RegisterAttached("ConfirmChange", typeof(bool), typeof(Selector), new PropertyMetadata(true, ConfirmChangeChanged)); public static void ConfirmChangeChanged(DependencyObject d, DependencyPropertyChangedEventArgs args) { Selector instance = d as Selector; if (args.NewValue is bool == false) return; if ((bool)args.NewValue) instance.SelectionChanged += OnSelectorSelectionChanged; else instance.SelectionChanged -= OnSelectorSelectionChanged; } static void OnSelectorSelectionChanged(object sender, RoutedEventArgs e) { Selector item = e.OriginalSource as Selector; MessageBox.Show("Unsaved changes. Are you sure you want to change teams?"); } } } This is used in XAML as this: <UserControl x:Class="AttachedBehaviours.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:this="clr-namespace:AttachedBehaviours" mc:Ignorable="d"> <Grid x:Name="LayoutRoot"> <StackPanel> <ComboBox ItemsSource="{Binding Teams}" this:ConfirmChangeBehaviour.ConfirmChange="true" > </ComboBox> </StackPanel> </Grid> </UserControl> I am getting an error: Unknown attribute ConfirmChangeBehaviour.ConfirmChange on element ComboBox. [Line: 13 Position: 65] Intellisense is picking up the behavior, why is this failing at runtime? Thanks, Mark EDIT: Register() changed to RegisterAttached(). Same error appears.

  • wpf datagrid current item binding

    - by tk
    I want to bind a content of Label to the selected item of a datagrid. I thought the 'current item' binding expression would work, but it is not. My xaml code and code-behind c# is like below. <Window x:Class="WpfApplication2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="512" Width="847"> <DockPanel LastChildFill="True"> <Label Content="{Binding Data/colA}" DockPanel.Dock="Top" Height="30"/> <DataGrid ItemsSource="{Binding Data}"></DataGrid> </DockPanel> </Window> namespace WpfApplication2 { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); this.DataContext = new MyData(); } } public class MyData { DataTable data; public MyData() { data = new DataTable(); data.Columns.Add("colA"); data.Columns.Add("colB"); data.Rows.Add("aa", 1); data.Rows.Add("bb", 2); } public DataTable Data { get { return data; } } } } The label shows the first item of the DataTable, and does not change when i select other items on the datagrid. It seems the current item of dataview does not change. What should i do to bind it to the current selected item of datagrid?

  • Programming language shootout: code most like pseudocode for Dijkstra's Algorithm

    - by Casebash
    Okay, so this question here asked which language is most like executable pseudocode, so why not find out by actually writing some code! Here we have a competition where I will award a 100 point bounty (I know its not much, but I am poor after the recalc) to the code which most resembles this pseudocode. I've read through this a few times so I'm pretty sure that this pseudocode below is correct and about as unambiguous as pseudocode can be. Personally, I'm going to have a go in Python and probably Haskell as well, but I'm just learning the later so my attempt will probably be pretty poor. Note: Obviously to implement anything looking like this you'll have to define quite a few library functions. define DirectedGraph G with: Vertices as V, Edges as E define Vertex A, Z declare each e in E as having properties: Boolean fixed with: initial=false Real minSoFar with: initial=0 for A else infinity define PriorityQueue pq with: objects=V initial=A priority v=v.minSoFar create triggers for v in V: when v.minSoFar event reduced then pq.addOrUpdate v when v.fixed event becomesTrue then pq.remove v Repeat until Z.fixed==True: define Vertex U=pq.pop() U.fixed=True for Edge E adjacentTo U with other Vertex V: V.minSoFar=U.minSoFar+length(E) if reducesValue return Z.name, Z.minSoFar

    I am trying to install NServiceBus onto a clustered win2k3 host. The configuration utility provided (runner.exe) throw some errors that I did not catch, and it now runs correctly.

  • Binding from View-Model to View-Model of a child User Control in Silverlight? 2 sources - 1 target..

    - by andrej351
    Hi there, So i have a UserControl for one of my Views and have another 'child' UserControl inside that. The outer 'parent' UserControl has a Collection on its View-Model and a Grid control on it to display a list of Items. I want to place another UserControl inside this UserControl to display a form representing the details of one Item. The outer / parent UserControl's View-Model already has a property on it to hold the currently selected Item and i would like to bind this to a DependancyProperty on the inner / child UserControl. I would then like to bind that DependancyProperty to a property on the child UserControl's View-Model. I can then set the DependancyProperty once in XAML with a binding expression and have the child UserControl do all its work in its View-Model like it should. The code i have looks like this.. Parent UserControl: <UserControl x:Class="ItemsListView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" DataContext="{Binding Source={StaticResource ServiceLocator}, Path=ItemsListViewModel}"> <!-- Grid Control here... --> <ItemDetailsView Item="{Binding Source={StaticResource ServiceLocator}, Path=ItemsListViewModel.SelectedItem}" /> </UserControl> Child UserControl: <UserControl x:Class="ItemDetailsView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" DataContext="{Binding Source={StaticResource ServiceLocator}, Path=ItemDetailsViewModel}" ItemDetailsView.Item="{Binding Source={StaticResource ServiceLocator}, Path=ItemDetailsViewModel.Item, Mode=TwoWay}"> <!-- Form controls here... --> </UserControl> The selected Item is bound to the DependancyProperty fine. However from the DependancyProperty to the child View-Model does not. It appears to be a situation where there are two concurrent bindings which need to work but with the same target for two sources. Why won't the second (in the child UserControl) binding work?? Is there a way to acheive the behaviour I'm after?? Cheers.

  • Java conditional operator ?: result type

    - by Wangnick
    I'm a bit puzzled about the conditional operator. Consider the following two lines: Float f1 = false? 1.0f: null; Float f2 = false? 1.0f: false? 1.0f: null; Why does f1 become null and the second statement throws a NullPointerException? Langspec-3.0 para 15.25 sais: Otherwise, the second and third operands are of types S1 and S2 respectively. Let T1 be the type that results from applying boxing conversion to S1, and let T2 be the type that results from applying boxing conversion to S2. The type of the conditional expression is the result of applying capture conversion (§5.1.10) to lub(T1, T2) (§15.12.2.7). So for false?1.0f:null T1 is Float and T2 is the null type. But what is the result of lub(T1,T2)? This para 15.12.2.7 is just a bit too much ... BTW, I'm using 1.6.0_18 on Windows. PS: I know that Float f2 = false? (Float) 1.0f: false? (Float) 1.0f: null; doesn't throw NPE.
