NullPointerException when no invoker proxy bindings configured
--------------------------------------------------------------

                 Key: JBAS-5475
                 URL: http://jira.jboss.com/jira/browse/JBAS-5475
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: JBossAS-4.2.2.GA
         Environment: RHEL 4
JDK 1.6
            Reporter: Dan Ciarniello


When no invoker proxy bindings are configured, org.jboss.metadata.BeanMetaData.getInvokerBindings() returns a NullPointerException.  This is caused by the fix for JBAS-4444.  org.jboss.metadata.ConfigurationMetaData.getInvokers() used to return a zero-length array when no bindings were configured but it now returns a null value which BeanMetaData.getInvokerBindings() does not properly handle:

   public Iterator getInvokerBindings()
   {
      if (invokerBindings == null)
      {
         // See if there is a container default invoker name
         String[] defaultNames = configuration.getInvokers();
         if (defaultNames.length > 0)                               // Line 263 NPE
         {
            invokerBindings = new HashMap();
            for (int count = 0; count < defaultNames.length; count++)
            {
               invokerBindings.put(defaultNames[count], getJndiName());
            }
         }
         else
         {
            // Use the hard-coded defaults
            defaultInvokerBindings();
         }
      }

      return invokerBindings.keySet().iterator();
   }

Changing line 263 to if(defaultNames!=null && defaultNames.length()>0) would eliminate the NPE.
