NPE when calling operations on inactive modcluster subsystem
------------------------------------------------------------

                 Key: AS7-3027
                 URL: https://issues.jboss.org/browse/AS7-3027
             Project: Application Server 7
          Issue Type: Bug
          Components: Clustering
    Affects Versions: 7.1.0.Beta1b
            Reporter: Jesse Jaggars
            Assignee: Paul Ferraro


Despite not being able to 'see' the modcluster subsystem as illustrated below:
[domain at localhost:9999 subsystem] pwd
/host=master/server=server-one/subsystem
[domain at localhost:9999 subsystem] ls
cmp                 datasources         ee                  ejb3
infinispan          jacorb              jaxrs               jca
jdr                 jmx                 jpa                 logging
mail                messaging           naming              osgi
remoting            resource-adapters   sar                 security
threads             transactions        web                 webservices

I can still call methods on that subsystem. However when I do this, there is a NullPointerException thrown by the operation code.

[domain at localhost:9999 /] /host=master/server=server-one/subsystem=modcluster/:read-proxies-configuration
{
    "outcome" => "failed",
    "result" => undefined,
    "failure-description" => "JBAS014749: Operation handler failed: null",
    "rolled-back" => true
}

And the log/stacktrace is:

[Server:server-one] 11:39:45,518 ERROR [org.jboss.as.controller.management-operation] (pool-1-thread-3) JBAS014612: Operation ("read-proxies-configuration") failed - address: ([("subsystem" => "modcluster")]): java.lang.NullPointerException
