[jbossseam-issues] [JBoss JIRA] Reopened: (JBSEAM-1681) NPE thrown when tomcat shutsdown

[ http://jira.jboss.com/jira/browse/JBSEAM-1681?page=all ] Michael Youngstrom reopened JBSEAM-1681: ---------------------------------------- However, with tomcat 6 I get a similar exception when starting up the server. Looking at JavaBeanInterceptor.readResolve(JavaBeanInterceptor.java:160) it looks like that JavaBeanInterceptor is expecting an IllegalStateException to be thrown which will happen if Lifecycle used getApplication() instead of the static variable. So perhaps the fix for this issue is to use Lifecycle.getApplication() wherever Lifecycle.application is used in Lifecycle so this exception will go away and tomcat 55 will get IllegalStateExceptions instead of NPEs when shutting down. Unless I hear otherwise I'll go ahead and make the change. java.lang.NullPointerException at org.jboss.seam.contexts.BasicContext.get(BasicContext.java:48) at org.jboss.seam.Component.forName(Component.java:1710) at org.jboss.seam.Seam.componentForName(Seam.java:288) at org.jboss.seam.intercept.RootInterceptor.getComponent(RootInterceptor.java:222) at org.jboss.seam.intercept.JavaBeanInterceptor.readResolve(JavaBeanInterceptor.java:160) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:64) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:615) at java.io.ObjectStreamClass.invokeReadResolve(ObjectStreamClass.java:1088) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1747) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1324) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:362) at org.apache.catalina.session.StandardSession.readObject(StandardSession.java:1439) at org.apache.catalina.session.StandardSession.readObjectData(StandardSession.java:942) at org.apache.catalina.session.StandardManager.doLoad(StandardManager.java:394) at org.apache.catalina.session.StandardManager.load(StandardManager.java:321) at org.apache.catalina.session.StandardManager.start(StandardManager.java:637) at org.apache.catalina.core.ContainerBase.setManager(ContainerBase.java:438) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4255) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:791) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:771) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:525) at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:825) at org.apache.catalina.startup.HostConfig.deployWARs(HostConfig.java:714) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:490) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:1138) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:311) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:117) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1053) at org.apache.catalina.core.StandardHost.start(StandardHost.java:719) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:443) at org.apache.catalina.core.StandardService.start(StandardService.java:516) at org.apache.catalina.core.StandardServer.start(StandardServer.java:710) at org.apache.catalina.startup.Catalina.start(Catalina.java:566) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:64) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:615) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:288) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
