Resolution: Done
> NPE when undeploying node in a cluster
> --------------------------------------
>
> Key: EJBTHREE-117
> URL: http://jira.jboss.com/jira/browse/EJBTHREE-117
> Project: EJB 3.0
> Type: Bug
> Components: Clustering
> Versions: Preview 4
> Reporter: Kabir Khan
> Assignee: Kabir Khan
> Fix For: Preview 5
>
>
> > The stuff below is before clustering steps in. If you run the
> > clustering example (or I think any for that matter, but haven't
> > tried), and shut down one of the servers gracefully:
> -It starts undeploying
> -Entries in AOP Dispatcher are removed
> -When the client next tries to connect to the closing down server, the
> > server is still "up", but there is no entry in AOP Dispatcher (target is
> > null). It tries to use the null target, and it fails with a NPE which is
> > propagated all the way up to the client
> >
> > The client code is:
> > public static void main(String[] args) throws Exception
> > {
> > InitialContext ctx = new InitialContext();
> > Session remote = (Session) ctx.lookup(Session.class.getName());
> > while (true)
> > {
> > remote.test(); //Fail here
> > Thread.sleep(1000);
> > }
> > }
