ACTUAL BEHAVIOR
---------------
The process design has a parallel complex gateway.
Within that gateway one of the threads has a human task with an interrupting boundary timer.
When the timer expires, the Human Task is completed but the BPM instance is not moved to the next activity.

At the same time, the following error is observed in the diagnostic logs :

"Thread count now < 0. This MUST NOT happen as it will cause routing problems. Please report this incident"
 
java.lang.Throwable
  at com.collaxa.cube.engine.util.ThreadCountManager.decreaseThreadCount(ThreadCountManager.java:56)
  at oracle.bpm.bpmn.engine.model.runtime.microinstructions.MIDecreaseThreadCount.doExecute(MIDecreaseThreadCount.java:28)
  at oracle.bpm.bpmn.engine.microkernel.MIBase.execute(MIBase.java:34)
  at oracle.bpm.bpmn.engine.microkernel.MISequenceBlock.doExecute(MISequenceBlock.java:68)


EXPECTED BEHAVIOR
-----------------------
The BPM should advance to the next activity
