Platform issue for jBPM-2959
Comment 1 Martin Weiler 2010-10-13 10:12:46 UTC 
Link: Added: This issue depends JBPM-2959
Comment 4 Alejandro Guizar 2010-10-26 20:18:57 UTC 
The underlying support case is related to insertion locking issues specific to MySQL 5.0 that do not affect 5.1 and later MySQL versions.
Deferring, but not rejecting, as more problems concerning the job executor acquisition strategy might surface in the future.
Comment 5 Alejandro Guizar 2010-10-28 02:57:34 UTC 
Retaking issue as SOA-2365 is on hold.
Comment 6 Alejandro Guizar 2010-11-10 07:17:14 UTC 
Project issue JBPM-2959 resolved. Dispatcher thread has been backported from jBPM 4.
Comment 7 Martin Weiler 2011-02-09 19:54:45 UTC 
Closing as the underlying JBPM-2959 issue has been closed and resolved already.
Comment 8 David Le Sage 2011-02-25 04:39:08 UTC

Release Notes Text: Added: https://issues.jboss.org/browse/JBPM-2959

The dispatcher thread from jBPM 4 has been backported to this release.  This fixes a race condition that appeared in  in multiple JobExecutor threads which was caused by locking issues specific to MySQL 5.0. These locking issues do not affect later MySQL versions. As a result of this fix, users will no longer encounter race conditions in this scenario if using MySQL.
