This seems to throw a NPE sometimes. Apparently the registry is null!
With sometimes I mean following.
I have two machines, development and production. Both run JBoss 5.1.0
with Liferay 6.0.6 Portal. The production machine works fine, but
development machine fails when deploying BIRT Viewer.
Same thing with 3.7.0 and 3.7.1.
I'm not sure if this is a bug or not. Maybe the dev machine has
something wrong. The birt.war in both is exactly same copy.
What might cause this?

They should be identical installations. The error happens when deploying
the war, or starting the AS. Running a report then says that there is
not /birt. It does not deploy.

You may need to log a bug for this. I have not seen this error. You
may also want to see if deploying the viewer to JBoss manually works as
a test.
