Remy,
What I am trying to do is start a discussion of _what_ the behaviour should be,
so it can be fixed. I already consider the current behaviour to be broken.
For example deploying a war on starutp, then undeploying it on shutdown
adds unnecessary overhead to the tomcat start/stop processing. This would
be a huge issue in a hosting environment where you might have 100's of war
files.
Regards,
Glenn
