JSR 360 and JSR 361: A Big Leap for Java ME 8
- by terrencebarr
It might have gone unnoticed to some, but Java ME took a big leap forward a couple of weeks ago with the filing of two new JSRs:
JSR 360: “Connected Limited Device Configuration 8″ (aka CLDC 8)
JSR 361: “Java ME Embedded Profile” (aka ME EP)
Together, these two JSRs will significantly update, enhance, and modernize the Java ME platform, and specifically small embedded Java, with a host of new features and functionality.
JSR 360 – Connected Limited Device Configuration 8
CLDC 8 is based on JSR 139 (CLDC 1.1) and updates the core Java ME VM, language support, libraries, and features to be aligned with Java SE 8. This will include:
VM updated to comply with the JVM language specification version 2
Support for SE 7/8 language features like Generics, Assertions, Annotations, Try-with-Resources, and more
New libraries such as Collections, NIO subset, Logging API subset
A consolidated and enhanced Generic Connection Framework for multi-protocol I/O
With CLDC 8, Java ME and Java SE are entering their next phase of alignment – making Java the only technology today that truly scales application development, code re-use, and tooling across the whole range of IT platforms, from small embedded to large enterprise.
JSR 361 – Java ME Embedded Profile
ME EP is based on JSR 228 (IMP-NG) and updates the specification in key areas to provide a powerful and flexible application environment for small embedded Java platforms, building on the features of CLDC 8:
A new, lightweight component and services model
Shared libraries
Multi-application concurrency, inter-application communication, and event system
Application management
API optionality, to address low-footprint use cases
With ME EP, application developers will have a modern application environment which allows development and deployment of modular, robust, sophisticated, and footprint-optimized solutions for a wide range of embedded use cases and devices.
Summary
While these JSRs are still under development, it’s clear that there are exciting new times ahead for Java ME – turning into a serious application platform while maintaining the focus on resource-constrained devices to address the expected explosion of small, smart, and connected embedded platforms.
