Peter Johnson af2f54720d Java: Don't detach thread when releasing globals. ...

JavaGlobal was unconditionally attaching to (okay) and detaching from (bad)
the current thread during destruction.  We don't want to do this if the
destructor gets called from an attached thread.  Instead, use GetEnv to
first try to get the environment, and only attach and detach if it returns
an error saying the thread is detached.

Also, make sure notifier callbacks appropriately free Java locals to avoid
running out of local variable space.
