Interesting, I ran into a similar, but still different issue. http://jira.jboss.com/jira/browse/JBPM-680 I saw that one of the tests was creating the scheduler thread w/ the default constructor, and: anonymous wrote : Changing lines 146 and 185 from: | new SchedulerThread().executeTimers(); | to: | new SchedulerThread( jbpmConfiguration ).executeTimers(); Perhaps your 'getSchedulerThread' method is doing a default constructor creation?
