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@localhost:9999 subsystem] pwd /host=master/server=server-one/subsystem [domain@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 weld I can still call methods on that subsystem. However when I do this, there is a NullPointerException thrown by the operation code.
