      public void doLeave(ActivityExecution execution)
      The default behaviour of BPMN, taking every outgoing sequence flow (where the condition evaluates to true), is not valid for an exclusive gateway. Hence, this behaviour is overriden and replaced by the correct behavior: selecting the first sequence flow which condition evaluates to true (or which hasn't got a condition) and leaving the activity through that sequence flow. If no sequence flow is selected (ie all conditions evaluate to false), then the default sequence flow is taken (if defined).
