I went back to a snapshot from 2004-01-10 and I'm still not seeing the
NPE on
shutdown using a jbossweb-tomcat50.sar/server.xml config with:
<Engine name="jboss.web" defaultHost="localhost"
autoDeploy="false" deployOnStartup="false">
What else does it take to produce this error?

Subject: Re: [JBoss-dev] Web integration (clustering) updates
I am able to reproduce the problem, but after spending a good bit of
time trying to find the bug, I am at a loss. Here is what I have found
so far (Scott maybe you would be able to figure it out based on this
info?).
The LoaderRepository variable, repository, within UnifiedClassLoader is
null when loadClassImpl() is called. Best I can tell, this probably
happens because UnifiedClassLoader::setRepository() is called with a
null value or UnifiedClassLoader::unregister() is called (am guessing it
is the later).
The MainDeployer does call the unregister() method on the
UnifiedClassLoader, but not until after it calls stop(), which is where
the NPE occurs (so has not gotten to the unregister() call yet).
My best guess is that the problem stems from destroying one of the sub
deployments (which happens before the NPE and will call unregister(),
but not familiar enough with classloader/deployment stuff to know if
would be using same UnifiedClassLoader instance).
I did notice an exception in the log before the NPE (am attaching
snippet of the log).
I also checked the MainDeployer, UnifiedClassLoader, and
UnifiedClassLoader3 for recent code changes. The MainDeployer had only
one change related to using a HashSet for the waitingForClasses
collection. The UnifiedClassLoader3 did not have any changes. The
UnifiedClassLoader had a lot of changes, but don't seem related to this
(but could be missing something).
