I think the rules are meat to apply to bytecode and JNI, otherwise they
could be trivially circumvented.

wait() is part of the JVM and I would not expect it to use JNI internally.

Unfortunately the JNI spec says nothing about this. I'm not aware of
anything in the JVMS 3e that addresses this either.
