Strange error: 'is not a valid value for 'NCName''

[m2spring]

I'm integrating the Activiti 5.9 engine into another Java application.
I have a couple of unit tests which execute test workflows and they have been succeeding for a while now.
Yesterday I upgraded my Designer to 5.9.1 (although 5.9.1 didn't produce different .bpmn files than 5.9).
My tests are failing with this log:

I can't make any sense out of the error messages relative to the .bpmn file.
What might be going on here?
Any pointer would be appreciated.

Hi,

That's very strange, because this BPMN 2.0 XML definition works fine in my Activiti Engine environment.
Can you create a unit test to reproduce the error?

Thanks,

[m2spring]

Yeah, the .bpmn is OK.

I'm integrating the engine into Jenkins as a Jenkins plugin.
The problem is happening only as a Junit / JenkinsTestCase, but not in regular Jenkins execution.
Which is good, because it basically works, but which is bad, because my test cases don't work.

I suspect there's some Jar version conflict behind this problem.
I just have seen a similar problem with xalan 2.6.0 / xalan 2.7.1 (with different symptoms).

I still haven't done all the research on the Jenkins / Junit side to understand what's going on.

Let me know, if you have some suspicion based on the given output.
