Hi Maciej,

Many thanks for your help , I was trying to upgrade  to jbpm  5.3 but I got some issues (hibernate with postgres).

For this issue :

- I'm throwing an exception from the rule just for test (this issue could happen in real life) and I understand  I should not throw exceptions from rules.

- In step 1 in the process definition a have this script action: System.out.println("PROCESS  step 1 "+kcontext.getProcessInstance()... I have this log trace many times in 60 second (timer period) and some times it does not stop(I should have only one).

Here some logs  :
