It seems that this issue specifically happens when using Service Tasks inside Swim Lane.

Version-Release number of selected component (if applicable):
- BPMS 6.0.2

How reproducible:
- Always using the attached "swimlaneProcess.bpmn2" process definition in Web Designer of BPMS 6.0.2

Steps to Reproduce:
1. Import the attached "swimlaneProcess.bpmn2" process definition in Web Designer
2. The Service Task contains the values specified for Interface and Operation properties
3. Save and validate it and it should throw the "java.lang.IllegalArgumentException: No interfaces found" ERROR as shown above.


Actual results:
- The server.log shows the "java.lang.IllegalArgumentException: No interfaces found" ERROR  during validation although Interface name was specified.

Expected results:
- There should be no validation error.

Additional info:
- NA

Comment 3 Kris Verlaenen 2014-11-05 14:21:19 UTC 
It seems that for service tasks outside swimlanes the BPMN2 XML correctly contains the <message> and <interface> elements above the <process>, when it is placed inside a swimlane, those elements are no longer available.  I assume that the script that transforms the drools:serviceinterface and drools:serviceoperation attributes on service task into <message> and <interface> elements is not taking composite nodes into account (as the same seems to happen with embedded sub-process).
