EAP5.1.2 is running with 'all' profile (./run.sh -c all) 3. import eap resource Actual results: 2012-08-14 13:11:18,400 WARN [InventoryManager.discovery-1] (rhq.core.pc.inventory.InventoryManager)- Failure during discovery for [Cache] Resources - failed after 1 ms. java.lang.Exception: Discovery component invocation failed. at org.rhq.core.pc.util.DiscoveryComponentProxyFactory$ComponentInvocationThread.call(DiscoveryComponentProxyFactory.java:297) at java.util.concurrent.FutureTask$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$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:679) Caused by: java.lang.NullPointerException at org.rhq.plugins.jbosscache3.JBossCacheDetailDiscoveryComponent.discoverResources(JBossCacheDetailDiscoveryComponent.java:83) at sun.reflect.GeneratedMethodAccessor26.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.rhq.core.pc.util.DiscoveryComponentProxyFactory$ComponentInvocationThread.call(DiscoveryComponentProxyFactory.java:293) Expected results: no exceptions Additional info: agent log attached --- Additional comment from hrupp on 2012-08-14 12:05:19 EDT --- Can you describe how to get the cache set up, to run into the above issue? I can see the place of the problem in the code, but would need a running instance of course to replicated. Is this on Oracle btw? --- Additional comment from hrupp on 2012-08-14 12:09:53 EDT --- Line 83 should probably be changed to beanName += ((jmxName==null || jmxName.equals("")) ? "" : "," + jmxName); as jmxName can probably be null - especially on Oracle, which treats empty strings as null. And the default config entry is: <plugin-configuration> <c:simple-property name="jmx-resource" default=""/> </plugin-configuration> --- Additional comment from hrupp on 2012-08-14 14:06:49 EDT --- This property is indeed null.
master b86e772ba8569 In addition to just fixing the NPE, it was needed to also put the jmx-name into the plugin configuration of the resource. Otherwise the inventory tab's connection properties would have complained that no jmxName is set. As the resource of type Cache has no jmxName (it basically forms the base name), it is marked as optional.
