NPE in during shutdown (JBoss Version: 3.2.3) OS: Win2K

SourceForge Submitter: vbkrishnan .
Server version: 3.2.3
OS: Win2K

There are a couple of issues during shutdown:

1. The destroy method of our servelet performs some
cleanup tasks which require accessing the beans. These
bean calls fail because the name space is no longer
known. These failures are not fatal since our code
catches the exceptions and handles them. However, we
lose the bookkeeping information because of this.

2. As the shutdown proceeds, it attempts to invlaidate
the cache for each entity bean and in each case NPE is
thrown from:
org.jboss.cache.invalidation.triggers.EntityBeanCacheBat
chInvalidatorInterceptor.stop

I have attached the server log which contains all the
logging from startup to shutdown.
