This was not fixed by not nulling the lock manager. The
problem was the EntityInstanceCache.m_container variable
being nulled and inadequate synchronization by the
passivation thread to validate the its container had not
been destroyed. I have tried to clean this up and the
exception is gone, but this code needs to be simplified as
there are too many locks and inner classes to track who
owns what.
