[jboss-jira] [JBoss JIRA] Assigned: (EJBTHREE-1260) Performance issue with EjbLinkDemandMetaData

Performance issue with EjbLinkDemandMetaData -------------------------------------------- Key: EJBTHREE-1260 URL: https://jira.jboss.org/jira/browse/EJBTHREE-1260 Project: EJB 3.0 Issue Type: Bug Components: core Affects Versions: AS 5.0.0.Beta4 Reporter: Guy Coleman Assignee: Carlo de Wolf We have an application with about 200 EJB3 SLSB and MDBs, 120 EJB2 entity beans and a few web apps. This takes about 1-2 minutes to start up with JBoss 4.2.2.GA. With 5.0.0.Beta4 this jumps to around 20-30 minutes. Some thread dumps show that it's spending most of its time here: "main" prio=6 tid=0x044b7430 nid=0x10b4 runnable [0x049cd000..0x049cf9f8] at java.lang.Throwable.fillInStackTrace(Native Method) at java.lang.Throwable.<init>(Throwable.java:196) at java.lang.Exception.<init>(Exception.java:41) at javax.management.JMException.<init>(JMException.java:35) at javax.management.OperationsException.<init>(OperationsException.java:36) at javax.management.MalformedObjectNameException.<init>(MalformedObjectNameException.java:35) at javax.management.ObjectName.construct(ObjectName.java:393) at javax.management.ObjectName.<init>(ObjectName.java:1304) at org.jboss.ejb3.dependency.EjbLinkDemandMetaData$EjbLinkDemandDependencyItem.resolve(EjbLinkDemandMetaData.java:134) at org.jboss.dependency.plugins.AbstractDependencyInfo.resolveDependencies(AbstractDependencyInfo.java:140) at org.jboss.dependency.plugins.AbstractController.resolveContexts(AbstractController.java:901) at org.jboss.dependency.plugins.AbstractController.resolveContexts(AbstractController.java:839) at org.jboss.dependency.plugins.AbstractController.resolveContexts(AbstractController.java:784) at org.jboss.dependency.plugins.AbstractController.change(AbstractController.java:622) at org.jboss.dependency.plugins.AbstractController.change(AbstractController.java:411) at org.jboss.system.ServiceController.doChange(ServiceController.java:659) at org.jboss.system.ServiceController.create(ServiceController.java:393) at org.jboss.system.ServiceController.create(ServiceController.java:358) at sun.reflect.GeneratedMethodAccessor212.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:157) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:96) at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:668) at org.jboss.system.ServiceMBeanSupport.create(ServiceMBeanSupport.java:186) Patching EjbLinkDemandMetaData to avoid creating ObjectNames for names that are obviously invalid speed this up considerably: the startup time is then about 5 minutes, though It still seems to spend a lot of time looping in that EjbLinkDemandDependencyItem .resolve
