Jon plugin - failing RebuildIndex operation on [MassIndexer] component ---------------------------------------------------------------------- Key: ISPN-3450 URL: https://issues.jboss.org/browse/ISPN-3450 Project: Infinispan Issue Type: Bug Reporter: Tomas Sykora Assignee: Mircea Markus 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) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.rhq.core.pc.inventory.ResourceContainer$ComponentInvocationThread.call(ResourceContainer.java:634) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722) 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.
