After playing with it more, the culprit seems to be not the symbolic link but the local drive :-/ When I delete the neo4j directory with the db and start the application from the local drive then I'm getting the NPEs - even if I shut the server down and start it again. When I delete the neo directory and start jboss from the directory on the nfs drive then it works fine, without NPEs. When I then start the application from the local drive again (without deleting the neo dir) then it again works fine, without NPEs. I have no idea why this is happening.. I verified that the index service is being initialized in the same thread that uses it later when the exception occurs so it shouldn't be a problem with some asynchronicity introduced by JBoss.
