Unable to load session snapshot Caused by: java.io.EOFException

nash.komar Mar 29, 2012 9:31 AM

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

... 117 more

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.
