Jackrabbit requires fairly recent versions of commons-collections. You will not that the two Jcr tests now fail since the previous apache version of the lib was reverted to JBoss.
Tom, can you figure out how we can live with the later version of Commons-Collections? I'm not sure what problem the new one was causing.
I have added the Jackrabbit libraries to the build.deploy.xml to be copied to the server/jbpm/lib directory.
This is necessary for the Jcr Service to run correctly.
