    Jbpm 3.3.1 Timer Exception on executionContext.leaveNode()

      Hi,

      In Jbpm 3.2.x, I never had this problem. But I recently upgraded to Jbpm 3.3.1, and now, on a State Node, if I have a timer set which repeats, and on the timers action I call executionContext.leaveNode(), I get an exception. If my timer is not set to repeat, I don't get the exception. This is a bit of a showstopper for me. Any ideas would be appreciated?

      Here is my simple process definition:

      <process-definition
 xmlns="urn:jbpm.org:jpdl-3.2" name="ITD Sick Leave">
 <swimlane name="Initiator"></swimlane>
 <start-state name="Record Sick Leave">
 <transition to="Wait for Tomorrow"></transition>
 </start-state>


 <state name="Wait for Tomorrow">
 <timer duedate="5 seconds" name="Wait for Tomorrow" repeat="5 seconds">
 <action class="za.co.workflow.itdsickleave.action.WaitForTomorrow"></action>
 </timer>
 <transition to="Complete"></transition>
 </state>


 <end-state name="Complete"></end-state>
</process-definition>


      Here is my action's execute method attached to the timer: 
      public void handle(ExecutionContext executionContext) throws Exception {
 executionContext.leaveNode();
 }


      Here is the exception being thrown:
