[ https://issues.jboss.org/browse/WFCORE-1049?page=com.atlassian.jira.plugi... ] Brian Stansberry commented on WFCORE-1049: ------------------------------------------ Here's one: http://brontes.lab.eng.brq.redhat.com/viewLog.html?buildId=75813&tab=... {code} 05:18:46,317 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-7) MSC000001: Failed to start service jboss.ra.deployer."ear_packaged.ear#ear_packaged2.rar".jboss.ironjacamar.resource: org.jboss.msc.service.StartException in service jboss.ra.deployer."ear_packaged.ear#ear_packaged2.rar".jboss.ironjacamar.resource: Failed to start service at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1904) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.NullPointerException at org.jboss.as.connector.services.resourceadapters.IronJacamarActivationResourceService.start(IronJacamarActivationResourceService.java:196) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1948) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1881) ... 3 more {code} The failing code is: {code} ManagementResourceRegistration cdRegistration = raRegistration.getSubModel(PathAddress.pathAddress(peCD)); ManagementResourceRegistration overrideCdRegistration = cdRegistration.registerOverrideModel(cm.getJndiName(), new OverrideDescriptionProvider() { {code} Dereferencing cdRegistration throws the NPE. It's null because raRegistration is a ref to an incompletely populated MRR. I found another failure of that test, and it was in a different spot in IronJacamarActivationResourceService but the same basic pattern -- getSubModel is called on an MRR and it unexpectedly returns null. These failures are hard to find in CI because its not a test method that fails, it's the preliminary ARQ setup (i.e. deployment) work. So you can't look up the test method in any test run and then check the history to find failures. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
