Problematic casting to String in org.jboss.jmx.connector.invoker.AuthenticationInterceptor
------------------------------------------------------------------------------------------

                 Key: JBAS-4344
                 URL: http://jira.jboss.com/jira/browse/JBAS-4344
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: JMX
    Affects Versions: JBossAS-4.0.4.GA
         Environment: Mac Os X, RedHat
            Reporter: David Dossot
         Assigned To: Dimitris Andreadis


There is a problematic cast in org.jboss.jmx.connector.invoker.AuthenticationInterceptor.invoke(Invocation invocation) on line 110:

  String opname = (String) obj[1];


When Twiddling to get a particular attribute, the following code is used in org.jboss.console.twiddle.command.GetCommand.execute(String[] args) on line 165:

  attributeNames.toArray(names);
  (...)
  AttributeList attrList = server.getAttributes(objectName, names);


So obj[1] ends up holding a String[] of attribute names (even if there is only one) and the cast fails:

14:14:44,760 ERROR [Twiddle] Exec failed
java.lang.ClassCastException: [Ljava.lang.String; cannot be cast to java.lang.String
