jRate 0.3.7.2 and 0.3.8.2beta-3.3.3 Released   2006-09-02 23:54 - jRate
Stable version 0.3.7.2 and beta version 0.3.8.2beta-3.3.3 of jRate are both now available for download. jRate is an extension of the GNU Java (GCJ) compiler front-end and runtime library which adds support for many of the features required by the Real-Time Specification for Java (RTSJ), including threading constructs with real-time constraints, asynchronous event handling, and memory regions. jRate was initially developed at Washington University in St. Louis, and it is released under the GPL (but including the usual GCC exception that non-GPLed programs may be compiled and linked with it).

Subversion Migration   2006-07-15 10:30 - jRate
The jRate project has migrated to using a Subversion repository. Anyone with a CVS checkout may want to review the Subversion access details at <http://sourceforge.net/svn/?group_id=126338> or browse the repository at <http://svn.sourceforge.net/jrate>. All new development will go on in the Subversion repository, CVS is no longer used for jRate.

Release on schedule for early September   2005-08-23 06:34 - jRate
The next release of jRate, version 0.4.0-3.3.3, is on schedule for an early September release. Only a few remaining bugs need to be squashed. CVS should be fairly stable now, if you're interested in getting a preview. New features include raw/physical memory access, admission control, priority inheritance/ceiling, thread memory allocation limiting, heap checks on the source compilation path, shared thread parameters, HighResolutionClock implementations for additional architectures, several bugfixes, and increased RTSJ compliance.

Stable version 0.3.7.1 and beta version 0.3.8.1beta-3.3.3 of jRate are both now available for download. jRate is an extension of the GNU GCJ compiler front-end and runtime system which adds support for most of the features required by the Real-Time Specification for Java (RTSJ), including threading constructs with real-time constraints, asynchronous event handling, and memory regions. jRate was initially developed at Washington University in St. Louis, and it is released under a license similar to GCC's GPL license (which allows for non-GPLed programs to be compiled and linked).

The next stable jRate release will be jRate-0.4.0-3.3.3, based on GCC-3.3.3. There will be a number of improvements and additions in this release. Among them:

• Sharable and dynamically-updatable thread parameters objects
• Memory-reference checks for NoHeapRealtimeThreads
• Memory area allocation rate and cumulative allocation limiting via MemoryParameters
• Raw and physical memory classes
• Per-object and system-wide MonitorControl policies: priority inheritance and priority ceiling
• Support for dropping root privileges after program is running
• Improved scope-awareness of some standard Java library classes
• Minimal feasibility analysis
• Bugfixes in the compiler and runtime
• Increased RTSJ spec-compliance
• Some build process improvements
• Some new demos included to test new features

Reference store checks are now emitted for .class-to-object and .java-to-object compilation paths and may be disabled with -fno-scope-check.

Heap access checks are emitted for the .class-to-object path in the current beta, and will also be supported for the .java-to-object path in the upcoming stable release. These checks may be disabled with -fno-heap-check.
