If you don't specify a statemanager on the destination manager in JBossMQ,
you get an infinite loop.

/**

• Gets the ID attribute of the JMSServer object
  *
• @return The ID value
  */
  public String getID()
  {
  String ID = null;

while (true)
{
try
{
synchronized (idLock)

{ ID = "ID:" + (new Integer(lastID++).toString()); }

stateManager.addLoggedOnClientId(ID);
break;
}
catch (Exception e)
{
}
}

The code interprets the NPE caused by a null statemanger as the generated client id is already logged in
and tries again, FOREVER.
