Description of problem:
jBPM Designer allows to set arbitrary value as a signalRef property of signal-catching boundary event. 6.1.3.CR1 contains a change in Bpmn2JsonUnmarshaller that requires the signalRef to be UUID string. If the process with non-UUID signalRef is imported in 6.1.3.CR1 it cannot be saved due to exception in parsing the signalRef into UUID. Also validation fails with message "Could not parse BPMN process".

Version-Release number of selected component (if applicable):
6.1.3.CR1

How reproducible:
-

Steps to Reproduce:
1. Import attached process into Designer.
2. Click save and view validation issues.

Actual results:

• Save fails with Error notification with "null" message, exception in server log.
• Validation fails to parse the process.

Expected results:
No errors.
