Our WebSphere Application Server started core dumping immediately after we
merged our hbase feature branch to our mainline. I've tracked this down to
Bytes use of theUnsafe. The IBM JRE supplies Unsafe, but apparently it doesn't
work worth a damn. I managed to temporarily work "around" the issue using some
AOP wizardry. Would it be possible to add some property check to the static
initializer to allow one to explicitly opt for the pure Java comparer?
