--- Comment #7 from Torsten Zuehlsdorff <[email protected]> ---
I'm closing this as [email protected] authoritatively explained that this is an
inherent i386 architectural limitation, not a bug in openjdk8. KVA_PAGES=512
creates a 2G/2G address space split leaving only ~700-800MB for userspace,
which is insufficient for Java 8's GC. The recommended solution is to use an
amd64 kernel with compat32.
