Note: I use Eclipse for development. I can do a lot of changes to code
while running Cocoon in Tomcat, but with JavaFlow, I need to restart
everytime I change the code. This made me think: maybe the problem is
related to class loading somehow.

I don't know if it's useful to place this information in bugzilla too.

Bart.
