[jboss-user] [JBoss jBPM] - nulpointer in slightly complicated process

Hi I have a process definition as shown in the link below. http://www.freeimagehosting.net/uploads/4963a9f1b7.jpg When I run it with all nodes set to "async" and all joins with lock="UPGRADE" and with multiple or single job executors I get a nullpointer exception. It fails wwhen exectuting the action in F. Below is the stack trace. Has anyone experienced this before or is the graph too complicated. I can post the acual process definition xml if you want it and maybe a test case org.jbpm.graph.def.GraphElement.executeAction(GraphElement.java:267) 2008-12-18 12:10:31,617 [JbpmJobExecutor:1] ERROR - action threw exception: null java.lang.NullPointerException at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:261) at java.lang.ClassLoader.loadClass(ClassLoader.java:299) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at org.jbpm.instantiation.Delegation.instantiate(Delegation.java:145) at org.jbpm.instantiation.Delegation.getInstance(Delegation.java:126) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:197) at org.jbpm.instantiation.Delegation_$$_javassist_4.getInstance(Delegation_$$_javassist_4.java) at org.jbpm.graph.def.Action.execute(Action.java:128) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:197) at org.jbpm.graph.def.Action_$$_javassist_61.execute(Action_$$_javassist_61.java) at org.jbpm.graph.def.GraphElement.executeAction(GraphElement.java:256) at org.jbpm.graph.def.Node.execute(Node.java:334) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:197) at org.jbpm.graph.def.Node_$$_javassist_47.execute(Node_$$_javassist_47.java) at org.jbpm.job.ExecuteNodeJob.execute(ExecuteNodeJob.java:27) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:197) at org.jbpm.job.Job_$$_javassist_52.execute(Job_$$_javassist_52.java) at org.jbpm.job.executor.JobExecutorThread.executeJob(JobExecutorThread.java:166) at org.jbpm.job.executor.JobExecutorThread.run(JobExecutorThread.java:60) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4197330#...
