Comment 1 nwallace 2008-11-10 13:05:40 UTC 
We need to have these fixes ported to the jBPM SOA branch:

Comment 3 Julian Coleman 2008-11-17 17:18:44 UTC 
The fix for this has been pulled up to the SOA branch by Tom Baeyens.
Comment 4 Dana Mison 2008-11-25 06:35:10 UTC 
Release Note: Concurrent JobExecutors can now process the same job in parallel
Comment 5 Martin Vecera 2008-11-25 15:39:27 UTC 
Darrin, this seems to me like something cool, that it can "now" do this in parallel, but it is a bug in fact. I'd omit the word "now". What do you think?
Comment 6 Dana Mison 2008-11-26 02:24:26 UTC 
Agreed.  Can you give me some (highlevel) details on what the cause of the bug was?  Then I can say something like "X no longer prevents Concurrent JobExecutors from processing the same job in parallel"
Comment 7 Martin Vecera 2008-11-26 11:56:45 UTC 
JobExecutor wasn't thread safe. Because of that different executors running in different threads were able to grab the same job from the queue for processing.
Comment 8 Dana Mison 2008-12-09 03:32:21 UTC 
Took me a while to get back to this one: to clarify the "processing in parallel" /was/ the bug and it no longer does this.

Release Note:
JobExecutor is now thread safe.  Different executors running in different threads will not long try to process the same job from the queue.
