Problem getting Java Streams in HP Tandem (Non-Stop)
- by AndreaG
Hi.
We are porting a simple Java application between Tandem NonStop systems, from G-Series to H-Series. Java version is 1.5.0_02.
When performing basic I/O tasks like getting output stream from or opening a client socket, we receive exceptions like
java.io.IOException: Value out of range
or
java.net.SocketException: Value out of range
("value out of range" is Tandem native jargon for, well, quite everything I suppose).
Has anybody got similar issues? i.e. I/O corruption while for example messing with JNI?
I suppose there is something wrong with the system, but where might it be?
Thank you.
EDIT:
adding snippets as requested
sample snippet (a) - using Runtime.exec () (adapted)
Properties envVars = new Properties();
Process p = r.exec("/bin/env");
envVars.load(p.getInputStream());
Stack trace (a):
java.io.IOException: Value out of range (errno:4034)

Last line fails, and output gets redirected to console (!).
sample snippet (b) - using HttpURLConnection:
public WorkerThread (HttpURLConnection conn, String requestData, Logger logger)
{
this.conn = conn;
...
}
public void run ()
{
OutputStream out = conn.getOutputStream ();
}

Case (a) can be avoided because it was a workaround for other issues with previous JRE version (!), but same behaviour with sockets is really nasty.
