I don't see a reason, so it seems likely that somehow no one
has noticed before that this should be final (for thread safety and
optimizability). But it would be nice if someone with access to
full JCK etc tests made sure that adding "final" didn't break
anything.
I don't see a reason either. I checked the pre-OpenJDK history and it's
been like this since 1995. If it's deliberately non-final then I would
expect a comment.
I just built and ran the tests with it final and don't see any issues.
