Apparentely, this is an issue with the <distributable/> tag in web.xml. When I remove it, it deploys without errors. I found the workaround at
https://sourceforge.net/tracker/?func=detail&atid=376685&aid=617585&group_id=22866.

Hi,
I built the airline sample for jboss against a postgres db using the middlegen version I downloaded from cvs today. The sample build works fine and I drop the airline.ear file into the jboss deploy dir. The ejb's deploy ok but the war causes an NullPointerException in org.mortbay.j2ee.session.Manager.start(Manager.java:159). I've been stepping through the JBoss code with a debugger trying to figure out what's going on but haven't had any success so far. Has anyone seen this or figured it out?
Thanks,
Scott
The complete jboss log is...
