[jboss-user] [JBoss Messaging] - NullPointerException in org.jboss.remoting.Lease.notifyClien

Tuesday, 14 November 2006

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.run(Timer.java:462)
  |   | 
  | 
  | This is the exception that is thrown when a new JMS client tries to connect in step
7:
  | 
  | 
  |   |      [java] java.lang.RuntimeException: Error setting up client lease upon

  |   | 
  | 
  | 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.
