If you create/update a process and build the package in the guvnor, it will not be automatically reload in the jbpm console. The console is configured to load processes only on startup right now. This is the current situation in the 5.0.0 release.
This is just for your information.
from the #irc
currently the console is configured to load processes on startup and not dynamically reload, I'm updating the configuration to automatically update (as I agree that this is probably useful)
