I am running into an issue that I think I have seen previously, but I
don't remember how I solved it.. I had a custom portlet registered in
UserApp, and for some reason deleted it with the intentions of
re-registering it again. When I select the portlet branch under the
Portlet Admin page, all I get is:

PortletContainerImpl: failed to run the portlet:
'RegistrationPortlet'.

Any ideas what the problem could be? In the UserApp server.log I get
Ebo errors and NullPointer exceptions.
Here is an abridged version of the log:
