Yep, it should. Currently, auto-reload support only works for unpacked classes
in WEB-INF/classes. A note to that effect used to be in the release notes, but
perusing them now I see that this got snipped somewhere along the line -- I will
re-add it.
The underlying problem is that JAR files are not always released when you tell
them to be. The same problem affects redeploying from a WAR file (which Jon
isn't interested in, but others are :-).
See my next message for some proposed revisions to the Tomcat 4.0 release plan,
which will include working on this issue.
