I am seeing a strange issue in my jbpm 5 + hibernate + mysql configuration.
A test process 'com.sample.bpmn' consists of the following: start -> myactivityhandler -> somescript -> end
myactivityhandler is an async activity handler and hence 'execute' returns without calling completeWorkItem.
Now after execution of the following snippet:
..
ksession.startProcess("com.sample.bpmn");
..
I look at the ProcessInstanceInfo for the process and I see that the instance state is rightful set to ACTIVE since the process is actually active and just hit its first savepoint after the myactivityhandler.
However if I break the startprocess down to the following:
..
ProcessInstance pi = ksession.createProcessInstance("com.sample.bpmn", null);
ksession.startProcessInstance(pi.getId());
..
After execution of the above two, I expect the state would be the same as the previous snippet i.e. process instance state == ACTIVE but in reality it is set to PENDING. Also when I trace the SQL that hibernate is sending to MySQL I don't see any UPDATE going to the ProcessInstanceInfo table. This is a problem since now I can't complete the myactivityhandler workitem to continue the process.. and it needs to be started again.
Any clue why the above two scenarios are behaving differently?
Fwiw, if I configure the system to use the in-memory H2 then everything works fine and dandy.
Thanks
