Hi John, today I installed JDK8 b83 on one of the Jenkins build servers used by Apache Lucene: The problem with 32 bit JVMs and G1 collector is solved. I compared the trunk checkout of Lucene with both JVMs: In b82 it hangs, in b83 it passes. So I was able to re-enable 32 bit builds without the extra workaround stacksize option again.
Thanks for fixing this issue.
