Hi again,
I have a Timer and let it execute an action.
After the Timer execute the Action i got a Exception when the TimerThread want
to close his JBPMContext.
Can some one help and tell me what's wrong?

The Schedular:
| private void initSchedular () {
| // java SchedulerMain <interval> <historyMaxSize> <dateFormat>
|
| // create a new scheduler
| Scheduler scheduler = new Scheduler();
|
| // initialize it with the command line parameters
| int interval = 5000;
| scheduler.setInterval(interval);
| int historyMaxSize = 50;
| scheduler.setHistoryMaxSize(historyMaxSize);
| DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy
HH:mm:ss");
|
| // start the scheduler
| scheduler.start();
|
| // register the console listener
| scheduler.getSchedulerThread().addListener( new
LogListener(dateFormat) );
| }
|
The Exception
