EJB client can fail with CNFE when deserializing EJBException since wrapped cause might not be on classpath such as CacheException ---------------------------------------------------------------------------------------------------------------------------------- Key: WFLY-5788 URL: https://issues.jboss.org/browse/WFLY-5788 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 10.0.0.CR5 Reporter: Michal Vinkler Assignee: Radoslav Husar -RuntimeExceptions thrown when accessing the SFSB cache should be rethrown as an EJBException. Otherwise the client doesn't know how to serialize implementation specific exception classes.- This is not correct. The cause is wrapped in the EJBException but it is the cause that cannot be deserialized. Updated the Jira summary and crossed ^ out. --Rado Seen in our failover tests for remote stateful EJBs - scenarios. After failing a node, client logs these error messages: {code} 2015/11/27 04:10:03:241 EST [ERROR][Runner - 894] HOST perf17.mw.lab.eng.bos.redhat.com:rootProcess:c - Error getting response. <javax.ejb.EJBException: java.lang.ClassNotFoundException: org.infinispan.statetransfer.OutdatedTopologyException> javax.ejb.EJBException: java.lang.ClassNotFoundException: org.infinispan.statetransfer.OutdatedTopologyException at org.jboss.ejb.client.EJBInvocationHandler.doInvoke(EJBInvocationHandler.java:238) at org.jboss.ejb.client.EJBInvocationHandler.doInvoke(EJBInvocationHandler.java:183) at org.jboss.ejb.client.EJBInvocationHandler.invoke(EJBInvocationHandler.java:146) at com.sun.proxy.$Proxy2.getSerialAndIncrement(Unknown Source) at org.jboss.smartfrog.clustering.ejb3.StatefulSBProcessorFactoryImpl$EJB3RequestProcessor.processRequest(StatefulSBProcessorFactoryImpl.java:84) at org.jboss.smartfrog.loaddriver.CompoundRequestProcessorFactoryImpl$CompoundRequestProcessor.processRequest(CompoundRequestProcessorFactoryImpl.java:52) at org.jboss.smartfrog.loaddriver.Runner.run(Runner.java:103) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.ClassNotFoundException: org.infinispan.statetransfer.OutdatedTopologyException at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at org.jboss.marshalling.AbstractClassResolver.loadClass(AbstractClassResolver.java:131) at org.jboss.marshalling.AbstractClassResolver.resolveClass(AbstractClassResolver.java:112) at org.jboss.marshalling.river.RiverUnmarshaller.doReadClassDescriptor(RiverUnmarshaller.java:948) at org.jboss.marshalling.river.RiverUnmarshaller.doReadNewObject(RiverUnmarshaller.java:1255) at org.jboss.marshalling.river.RiverUnmarshaller.doReadObject(RiverUnmarshaller.java:276) at org.jboss.marshalling.river.RiverUnmarshaller.doReadObject(RiverUnmarshaller.java:224) at org.jboss.marshalling.river.RiverUnmarshaller.readFields(RiverUnmarshaller.java:1745) at org.jboss.marshalling.river.RiverObjectInputStream.defaultReadObject(RiverObjectInputStream.java:81) at java.lang.Throwable.readObject(Throwable.java:914) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.jboss.marshalling.reflect.SerializableClass.callReadObject(SerializableClass.java:307) at org.jboss.marshalling.river.RiverUnmarshaller.doInitSerializable(RiverUnmarshaller.java:1637) at org.jboss.marshalling.river.RiverUnmarshaller.doInitSerializable(RiverUnmarshaller.java:1606) at org.jboss.marshalling.river.RiverUnmarshaller.doInitSerializable(RiverUnmarshaller.java:1606) at org.jboss.marshalling.river.RiverUnmarshaller.doInitSerializable(RiverUnmarshaller.java:1606) at org.jboss.marshalling.river.RiverUnmarshaller.doReadNewObject(RiverUnmarshaller.java:1285) at org.jboss.marshalling.river.RiverUnmarshaller.doReadObject(RiverUnmarshaller.java:276) at org.jboss.marshalling.river.RiverUnmarshaller.doReadObject(RiverUnmarshaller.java:209) at org.jboss.marshalling.AbstractObjectInput.readObject(AbstractObjectInput.java:41) at org.jboss.ejb.client.remoting.InvocationExceptionResponseHandler$MethodInvocationExceptionResultProducer.getResult(InvocationExceptionResponseHandler.java:79) at org.jboss.ejb.client.EJBClientInvocationContext$1.run(EJBClientInvocationContext.java:282) at java.security.AccessController.doPrivileged(Native Method) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:279) at org.jboss.ejb.client.EJBObjectInterceptor.handleInvocationResult(EJBObjectInterceptor.java:64) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:290) at org.jboss.ejb.client.EJBHomeInterceptor.handleInvocationResult(EJBHomeInterceptor.java:88) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:290) at org.jboss.ejb.client.TransactionInterceptor.handleInvocationResult(TransactionInterceptor.java:46) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:290) at org.jboss.ejb.client.ReceiverInterceptor.handleInvocationResult(ReceiverInterceptor.java:129) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:265) at org.jboss.ejb.client.EJBClientInvocationContext.awaitResponse(EJBClientInvocationContext.java:453) at org.jboss.ejb.client.EJBInvocationHandler.doInvoke(EJBInvocationHandler.java:204) ... 7 more {code} Link http://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/eap-7x-failover-ejb-e...
