Hi all, Back from a long vacation I decided to build a fresh engine from the tip of the ovirt-3.5 branch (447ff7) and to my dismay, the deployed build will not start within jboss. The following error seems of paramount importance (full log attached). Can anyone help me figure out what is going on? 2015-01-07 16:36:34,558 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-7) MSC00001: Failed to start service jboss.deployment.subunit."engine.ear"."bll.jar".component.Backend.START: org.jboss.msc.service.StartException in service jboss.deployment.subunit."engine.ear"."bll.jar".component.Backend.START: Failed to start service at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1767) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) [rt.jar:1.7.0_71] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) [rt.jar:1.7.0_71] at java.lang.Thread.run(Thread.java:745) [rt.jar:1.7.0_71] Caused by: java.lang.IllegalStateException: JBAS011048: Failed to construct component instance at org.jboss.as.ee.component.BasicComponent.constructComponentInstance(BasicComponent.java:163) at org.jboss.as.ee.component.BasicComponent.createInstance(BasicComponent.java:85) at org.jboss.as.ejb3.component.singleton.SingletonComponent.getComponentInstance(SingletonComponent.java:116) at org.jboss.as.ejb3.component.singleton.SingletonComponent.start(SingletonComponent.java:130) at org.jboss.as.ee.component.ComponentStartService.start(ComponentStartService.java:44) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1811) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1746) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] ... 3 more Caused by: javax.ejb.EJBException: Unexpected Error at org.jboss.as.ejb3.tx.CMTTxInterceptor.handleExceptionInOurTx(CMTTxInterceptor.java:163) at org.jboss.as.ejb3.tx.CMTTxInterceptor.invokeInOurTx(CMTTxInterceptor.java:230) at org.jboss.as.ejb3.tx.CMTTxInterceptor.requiresNew(CMTTxInterceptor.java:333) at org.jboss.as.ejb3.tx.SingletonLifecycleCMTTxInterceptor.processInvocation(SingletonLifecycleCMTTxInterceptor.java:56) at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288) [jboss-invocation-1.1.1.Final.jar:1.1.1.Final] at org.jboss.as.ejb3.component.interceptors.CurrentInvocationContextInterceptor.processInvocation(CurrentInvocationContextInterceptor.java:41) at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288) [jboss-invocation-1.1.1.Final.jar:1.1.1.Final] at org.jboss.as.ee.component.TCCLInterceptor.processInvocation(TCCLInterceptor.java:45) at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288) [jboss-invocation-1.1.1.Final.jar:1.1.1.Final] at org.jboss.invocation.ChainedInterceptor.processInvocation(ChainedInterceptor.java:61) [jboss-invocation-1.1.1.Final.jar:1.1.1.Final] at org.jboss.as.ee.component.BasicComponent.constructComponentInstance(BasicComponent.java:161) ... 9 more Caused by: java.lang.NoSuchFieldError: CONFIGURATION_FILE at org.ovirt.engine.core.extensions.mgr.ExtensionsManager.loadImpl(ExtensionsManager.java:193) <snip> -- Adam Litke
