[rules-users] drools flow - why after reloading some process previously completed workItems gets executed once again?

[gs76pl]

hi,

i've a simple drools flow process with one workItem (its execute method
simply prints some text) and one human task. I'm using
drools-persistence-jpa to save my process status and load it when
process/server crashes.
What i've noticed is that:
1. after starting process my processinfo table gets updated with a new
process status (P1)
2. my workItem (W1) runs correctly and prints a text
3. a human task gets created
 ----- when i stop my server at this point and restart my server executing
below steps
1. load the session using
JPAKnowledgeService.loadStatefulKnowledgeSession(myPreviousSessionId,....)
2. start the process

At this point previously completed workItem (W1) gets executed once again
and the same human task gets created !!

I thought that perhaps the issue is with my transactionManager not
committing steps but since i'm using local transaction (commit happens after
any process step) its very unlikely.
Is it a bug that the same workItem gets executed or is it intentional and
it's up to the developer to check somewhere else whether specific step has
been already finished or not..?
