64-Bit Excelsior JET: Beta 3 Available, JCK @100%

I am very pleased to report that the 64-bit version of Excelsior JET has passed the JCK! That means that nothing precludes us from shipping it commercially, from the legal standpoint. However, our own test/benchmark suite still points to a few issues that we need to fix before the final release.

As far as application performance is concerned, the 64-bit optimizing compiler has handled 97% of all methods in our internal beta 3 tests. There is still vast room for improvement, as we have not yet implemented a number of optimizations. But we believe it is good enough for many of you, so please do your own tests and tell us whether that is true!

Known Problem

In some rare circumstances, the beta 3 compiler may run out of memory. We have already identified the root cause, but the fix has arrived a bit too late for the beta 3 train. To work around that problem, add the following line to the top of the project build script created by the JET Control Panel:

set jetvmprop=-Djet.gc.heaplimit=1024m

and run that script to build your project.

Feedback

The best way to report a bug is to select the Open Support Ticket item in the Help menu. That would automatically fill in the fields concerning your operating system version and hardware configuration.
