Example:
CastorPsmlManager
1) You somehow screw up your map location
2) Early init tries to load map and fails. Throws InitializationException
3) Late init method is called and waits for early method to finish, but it never will
You might have a service that is failing to initialize and just sleeping forever. Hopefully though, the Jetspeed log file would have the InitialzationException logged so you could determine what service is failing.

If you're webapp hangs, the issue is usually one of these 3:
1. thread deadlock
2. infinite loop
3. infinitely waiting for I/O
For 1., it should be difficult to reproduce on different systems with
different conditions but otherwise it's a mess to debug :( Let's assume
it's not a deadlock
For 2., try to request the page that hangs and let the request run while
you have lunch... if when you come back, you have a StackOverflow error,
you know you have an infinite loop somewhere :)
For 3., it looks to me like the most likely issue, check that your webapp
connects to the database server and sends queries by logging the sessions
on the DB server side (I don't known if MySQL has any debug facilities for
these
if it doesn't, snoop or tcpdump are your friends)
