I do not get it either. jBPM retrieves all processdefinitions with the same
name (how many can that be, just several I think) and loops over that.
I again urge you to log additional things, you might e.g. have a problem with a
reverse dns lookup why things take long...
So I would not file a
Processdefinition ID != name afaik.

You say you have you configured your identity service in the jbpm
configuration. The class needs to be available on java the classpath somewhere,
whether in an ear, a war or in a lib folder.
Could also be that the specific config us not picked up contrary to what you
expect. By making a big

Since you have a transition from task3 to the join, it is in the incoming
transitions and the join expects an incomming token/execution. It cannot easily
decide there will not be a token comming from task3.
Two things come to mind:
- implement your own join node
- use the n-out-of-m
please make a unittest for it and add it to the issue. All jbpm tests still
run, so maybe you do something that is either not tested or by accident worked

Try searching for 'identity service' and things like

No need to replicate data then.

I agree that the task should show up only once. I think you ran into a
non-tested issue here. Please file a jira issue for this and preferably add a
unit test to it.

Sorry...
Personal remark:
I'm more in favour of using
| variable read=true write=false required=true name=var1 /
|
instead of
| variable access=read,required name=var1/
|
and all should support EL for the value, not just static booleans
