Hi all,

I have an application based on seam 2.2.2 and jbpm 5.2 running under Jboss server 5.1.

I am facing the flowing exception when restarting the jboss server (5.1), but not all the time.


Caused by: java.io.EOFException

I did some debugging and the problem is coming from this line  in  org.jbpm.marshalling.impl.ProcessMarshallerImpl.readProcessTimers(...

  public void readProcessTimers(MarshallerReaderContext inCtx) throws IOException, ClassNotFoundException {
        inCtx.readersByInt.put( PersisterEnums.PROCESS_TIMER,  new TimerManager.ProcessTimerInputMarshaller());

        ObjectInputStream stream = inCtx.stream;

        TimerManager timerManager = ((InternalProcessRuntime) ((InternalWorkingMemory) inCtx.wm).getProcessRuntime()).getTimerManager();
        timerManager.internalSetTimerId( stream.readLong() );


        int token;
*   while ((token = inCtx.readShort()) != PersisterEnums.END) {*
|        | switch( token ) { |
|              | case PersisterEnums.TIMER : { |
|                  | TimerInstance timer = readTimer( inCtx ); |

*                                   ....*

I can not load the ksession.

if you have any solution or explanation, this will be very helpful.
