JBPM 5.4 PoC on task timeout

JBPM experts only please... We need a PoC, along with a detailed documentation on how to draw a JBPM 5.4 business process having one or more human tasks, that automatically proceed to next tasks if the original task is not processed within a certain predefined amount of time Kindly note the following: 1. We need to be able to configure this timeout transition in several tasks in the same process diagram with different timeout values, and each task should timeout independently 2. Status of the task should be changed to "Completed" when the task timeout occur... Which means that the process instance should not remain active waiting for user intervention on a task that had already timed-out when all other tasks are completed 3. If coding is needed, we need it to be very simple and generic to be used across several processes later on
