Hello,
I am trying to port process definition from one machine (Ubuntu) to other machine
(Windows) designed with JBPM GPD version 3.1.3.
I am facing NPE when I try to launch it on Windows machine. In workspace/.metadata/log I
can see the folowing trace:

Ok, obviously there is some problem in my process definition, but from the log, I cannot
figure out, what exactly.
Is there a way, or plan for the future to make GPD error more informative, e.g to point to
the Node, or any element which is malformed.
Thanks for the answer.
For the reference, here are the files:
best,
Milan
