Deadlock in org.jboss.as.ejb3.remote.protocol.versionone.MethodInvocationMessageHandler

XMLWordPrintable

      Class:

      org.jboss.as.ejb3.remote.protocol.versionone.MethodInvocationMessageHandler

      Method: 

      public void processMessage(ChannelAssociation, MessageInputStream) throws IOException;

      This code fragment:

      try {
    methodParams[i] = unmarshaller.readObject();
} catch (ClassNotFoundException cnfe) {
   /.../
   return;
}

      doesn't catch java.lang.IllegalArgumentException.
      This causes the server hangs.

      Example stacktrace: 

      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)

      I caught java.lang.Exception. It helps.
