Hi Michal!

I have a similar process like you and your patch works great!

But when I tried to run a more complex process, I got the ConstraintViolationException again.
I took your processes p1 and p2 and added a process p3:

<?xml version="1.0" encoding="UTF-8"?>

<process name="p3"
    schemaLocation="http://jbpm.org/4.0/jpdl http://docs.jboss.org/jbpm/xsd/jpdl-4.0.xsd"

    <start g="143,27,80,40" name="start">
        <transition g="-54,-22" name="to fork1" to="fork1" />

    <fork g="143,117,48,48" name="fork1">
        <transition g="-38,-22" name="to p2" to="p2" />
        <transition g="34,-14" name="to p2 (2)" to="p2 (2)" />

    <sub-process g="18,227,92,52" name="p2" sub-process-key="p2">
        <transition to="join1" />

     <sub-process g="18,227,92,52" name="p2 (2)" sub-process-key="p2 (2)">
        <transition to="join1" />

    <join g="141,334,48,48" name="join1">
        <transition to="end" />

    <end g="141,446,80,40" name="end" />


The process p3 just call two concurrent subprocesses to p2. And I changed the subprocess in p1 from p2 to p3.
So process p1 calls p3 that calls p2 two times in concurrent patchs.  p1 -> p3 -> (2x) p2

The ConstraintViolationException throws after ending the first p2 execution.
Do you know why?
