You will need to set the heap size for the benchmarks if you're running them manually. The dacapo test set has predefined heap sizes. You can find those in testing/tests/dacapo/build.xml .

There are more test sets in testing/tests but not all of them are readily usable. The following ones should mostly work:
- basic and opttests should always pass on x86/x64 (TestSysCalls fails on PowerPC)
- jni should always pass on x86/x64 (TestNestedGC fails on PowerPC)
- gctest should mostly pass (Exhaust fails sometimes, ReferenceTest fails sometimes on a few collectors, InlineAllocations fails when only using opt compiler)

I've attached an example test run file with protoype-opt and dacapo. You can put it into build/test-runs and then use it with Ant or buildit. Depending on how much functional testing you want to do, it may be profitable to use "development" instead of "protoype-opt".


Kind regards,

Erik Brangs
