I don't use parallel deployment.
To redeploy a webapp, I just replace the old war file with a new one and wait
for Tomcat to redeploy it.
The logs on redeploy were this:
07.07.2011 00:24:09 org.apache.catalina.startup.HostConfig checkResources
INFO: Undeploying context []
07.07.2011 00:24:09 org.apache.catalina.core.StandardWrapper unload

SCHWERWIEGEND: The web application [] is still processing a request that has
yet to finish. This is very likely to create a memory leak. You can control the
time allowed for requests to finish by using the unloadDelay attribute of the
standard Context implementation.

("SCHWERWIEGEND" should read like "SEVERE")
You're right, it could have something to do with the old context since it was
still waiting for a request to finish. Maybe I can reproduce the NPE if I make
a servlet that takes a long time to finish the request, to see what was the
original exception that has been suppressed by the NPE.
