Re: Servlet.service() for servlet CXFServlet exception
Posted by Daniel Kulp <dk...@apache.org>.
Can you make sure you grab the latest 2.1 snapshot and try again? I
really cannot see how there can possibly be a NullPointerException on
line 93 of ChainInitiationObserver. The line is just:
exchange.put(Bus.class, bus);
which could only NPE if exchange is null, but that cannot be as the lines
above it would then NPE. Thus, I THINK something is out of sync with
our sources which will make debugging this not-easy. Tracing back
through the history, it looks like it may be picking up a 2.0.3 or older
ChainInitiationObserver class, which would be bad.
The only other thing I can suggest is to enable jpda debugging or similar
and trace through this in jboss and actually trace into that method and
figure out what really is null.
