Note that this was seen in an attempt to upgrade to Netty 4.0.26, but I believe it is still valid for Jython.

This looks like a classical deadlock, so I would suggest a classical solution:
Assure that locks are always acquired in the same order by all participants.
However, letting runFinalizer() in FinalizeTrigger acquire the monitor of
PySystemStateCloser.class should fix it and assure that Finalizers cannot
deadlock with PySystemStateCloser in general.
msg9589 (view) Author: Jim Baker (zyasoft) Date: 2015-03-07.14:52:08 
The solution of having runFinalizer() acquire the monitor of
PySystemStateCloser.class makes the most sense. Note that PySystemStateCloser runs closers in a specific order at shutdown, so we cannot simply use the finalizer mechanism to replace it.
