Hi,

Thanks to your question I have reread the JNI spec and it looks like we 
should on the contrary enable the JNI refs.
They are not needed in most cases because we store objects on the stack 
but if the native call stores object in the heap we may lose track of 
used objects and garbage collects them though we should not. I don't 
know why they have been disabled by helmer (?)

Thanks,
