x64 ExtremeAssertionsBaseBaseUsePrimitiveWriteBarriers is unstable

Description

The configuration ExtremeAssertionsBaseBaseUsePrimitiveWriteBarriers is quite unstable on x64. SPECjbb2005 fails reliably and many other benchmarks fail transiently, either due to NPEs, OutOfMemoryError or GC overhead limits.

It's not clear to me if this is a MMTk or a Jikes RVM problem.

I've seen similar failures before when the x64 porting test run still used SemiSpace so it's probably not a barrier problem.
