Hello everybody, 
I succeeded in filling jbpm5 ProcessInstanceInfo table while process is running, but when process ends the db record is deleted.
When a new process is created, its processId is correctly different from its predecessors.
Is this the expected behaviour? I was expecting to have these data permanently stored in ProcessInstanceInfo  table!

Here's my persistence.xml:
