Hi,
thanks for your replies.
If I leave out the -Xbootclasspath stuff, then it blows up because of
some clash (I think it uses its old javac.jar in the normal classpath
then). I can't check it right now, but iirc, it found the signer
information of some javac related class is different than the signer
information of another class in the same package or such.
I'm currently using it for testing. I can skip the compiler benchmarks
for now. However, it is a nice test-benchmark because it does lots and
lots of allocations, would be nice to have it working.
I hope SPEC releases an updated SPECjvm soon. It has been somewhat
broken since JDK8, and now even more...
Regards,
Roman
