NullPointerException when parsing process

Hi all,

we just upgraded from Activiti 5.11 to 5.12. Suddenly, the engine is not able to parse our processes (*.bpmn files) any more and crashes with a NullPointerException.

The processes were designed with Activiti Eclipse BPMN 2.0 Designer 5.11.2 and are read in and deployed without errors by the 5.11 engine.

Is there some kind of migration necessary to make 5.11 processes usable in 5.12? Am I missing something? The relevant stack trace is … not attached (Could not upload attachment to ./files/11030_727fe2b6224b2c87baa8e7bb6d866933.) but shown below.

Thanks!

Yes, there have been refactorings in that area. But the stacktrace isn't really learning me anything, all I can see is that probably the scope for the intermediate timer is not found … which is not expected of course.

Is there any chance you can upload a failing process? Or even email me personally if it is sensitive?
