This definitelly does not work because in CacheComponent.queryBean method there is a check
that ensures the MBean name has a type=Cache attribute. This is true for all cache
components but not for the mass indexing MBean which has type=Query. For this one the
method returns null, leading to the observed NPE.

An easy fix would be to add a type parameter to the method in question.

                 URL: https://issues.jboss.org/browse/ISPN-3450
             Project: Infinispan
          Issue Type: Bug
            Reporter: Tomas Sykora
            Assignee: Adrian Nistor

 RebuildIndex operation on [MassIndexer] component is failing while issuing in JON with
this error:
 java.lang.NullPointerException
 	at org.infinispan.rhq.CacheComponent.invokeOperation(CacheComponent.java:157)

 I reused configuration from ISPN test suite + I was able to issue this operation
successfully via jconsole tool. That's why I suspect that problems are somewhere in
JON-ISPN interaction or plugin.
