Deadlock in org.jboss.as.ejb3.remote.protocol.versionone.MethodInvocationMessageHandler --------------------------------------------------------------------------------------- Key: AS7-6086 URL: https://issues.jboss.org/browse/AS7-6086 Project: Application Server 7 Issue Type: Bug Components: EJB, Remoting Affects Versions: 7.1.3.Final (EAP) Environment: Doesn't matter. Reporter: Krzysztof Noceń Assignee: Eduardo Martins Fix For: No Release Class: {code} org.jboss.as.ejb3.remote.protocol.versionone.MethodInvocationMessageHandler {code} Method: {code} public void processMessage(ChannelAssociation, MessageInputStream) throws IOException; {code} This code fragment: {code} try { methodParams[i] = unmarshaller.readObject(); } catch (ClassNotFoundException cnfe) { /.../ return; } {code} doesn't catch *java.lang.IllegalArgumentException*. This causes the server hangs. Example stacktrace: {code} java.lang.IllegalArgumentException: No enum const org.example.ExampleEnum.ENUM_VALUE at java.lang.Enum.valueOf(Enum.java:196) at org.jboss.marshalling.river.RiverUnmarshaller.resolveEnumConstant(RiverUnmarshaller.java:1549) at org.jboss.marshalling.river.RiverUnmarshaller.doReadNewObject(RiverUnmarshaller.java:1293) at org.jboss.marshalling.river.RiverUnmarshaller.doReadObject(RiverUnmarshaller.java:272) at org.jboss.marshalling.river.RiverUnmarshaller.doReadObject(RiverUnmarshaller.java:209) at org.jboss.marshalling.AbstractObjectInput.readObject(AbstractObjectInput.java:37) at org.jboss.as.ejb3.remote.protocol.versionone.MethodInvocationMessageHandler.processMessage(MethodInvocationMessageHandler.java:164) at org.jboss.as.ejb3.remote.protocol.versionone.VersionOneProtocolChannelReceiver.handleMessage(VersionOneProtocolChannelReceiver.java:182) at org.jboss.remoting3.remote.RemoteConnectionChannel$5.run(RemoteConnectionChannel.java:429) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) {code} I caught *java.lang.Exception*. It helps.
