[jopr-issues] [JBoss JIRA] Commented: (JOPR-81) restarting jmx server makes hibernate entities stay unavailable

restarting jmx server makes hibernate entities stay unavailable --------------------------------------------------------------- Key: JOPR-81 URL: https://jira.jboss.org/jira/browse/JOPR-81 Project: Jopr Issue Type: Bug Components: Plugin - Hibernate Reporter: John Mazzitelli Assignee: John Mazzitelli Fix For: 2.2 How to repeat: See the steps for rhq-1600. After these steps, ctrl-C the java command you ran, wait a minute, and restart the same command as before. Now browse back to the hibernate entities for helloworld and notice they stay red forever. --- Stepping throught the code, this is caused by this NPE: Caused by: java.lang.NullPointerException at org.rhq.plugins.jmx.MBeanResourceComponent.loadBean(MBeanResourceComponent.java:101) at org.rhq.plugins.jmx.MBeanResourceComponent.getEmsBean(MBeanResourceComponent.java:143) at org.rhq.plugins.jmx.MBeanResourceComponent.getAvailability(MBeanResourceComponent.java:128) at sun.reflect.GeneratedMethodAccessor31.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.rhq.core.pc.inventory.ResourceContainer$ComponentInvocationThread.call(ResourceContainer.java:466) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) ... 3 more The debug output is "Call to org.rhq.plugins.hibernate.EntityComponent.getAvailability() with args [] failed." MBeanResourceComponent line 100-101 is: protected void loadBean() { Configuration pluginConfig = this.resourceContext.getPluginConfiguration(); The resourceContent is null. This is due to misusing the MBeanServerComponent API. (this was moved over from http://jira.rhq-project.org/browse/RHQ-1601 since this is Jopr plugin related)
