Have you checked out and built qa_refactor recently?Did you know, apart from JMM compliance and fixes for finalizer attacks and race conditions:
1. All hot spots are native methods.
2. The performance cost of security is 0%
3. Tests pass on these architectures; arm, sparc, x64
4. Tests pass on these OS'; Windows, Linux, OSX, Solaris
5. It builds and passes on other vendors JVM's, eg IBM's J9
6. The next frontier for performance improvement is reducing network
communication and or faster sockets.
7. Patience is rewarded.
Please check it out, build and test it and report any issues.
Cheers,
Peter.
