    NullPointerException in org.jboss.remoting.Lease.notifyClien

    Ralf Torsten Menche Newbie

      We are using Messaging 1.0.1.GA with JBoss 4.0.5.GA. We are experiencing a serious problem that prevents further client connections to JMS. It can be reproduced by the following steps:

      1. Start JBoss (standard messaging configuration).
      2. Start a JMS topic subscriber.
      3. Shutdown JBoss (client ExceptionListener is triggered, no action, client remains running).
      4. Restart JBoss.
      5. Stop JMS topic subscriber.
      6. After about a minute JBoss throws a NullPointerException.
      7. No further JMS connections will be accepted by the server.


      This is the server side exception from step 6:

      Exception in thread "Timer-1"
      java.lang.NullPointerException
       at org.jboss.remoting.Lease.notifyClientLost(Lease.java:211)
       at org.jboss.remoting.Lease.access$300(Lease.java:39)

       at java.util.TimerThread.mainLoop(Timer.java:512)
       at java.util.TimerThread.run(Timer.java:462)
      


      This is the exception that is thrown when a new JMS client tries to connect in step 7:

      TRACE output for remoting on the server indicates that the previous client lease is re-established early during step 4. I suppose the server's lease registration gets disturbed when the client is finally terminated in step 5.

      This is a major show stopper for us, as any client kept running during a server restart and terminated subsequently will render the JMS server unusable.

      Any suggestions appreciated.
