The JEP text is correct, it's the InputStreamReader or 
OutputStreamWriter instance that is used as the lock object.

Do you have any more context for the question? I'm wondering if you are 
observing a behavior change. The locking in this area was highly 
problematic and some of the undocumented and under-the-covers locking 
had to be adjusted. So far there hasn't been any feedback from anyone 
that has noticed anything but maybe you have?
