Testing now on 3.2.6.SP1 A bit more digging and I think I'm closer to the problem. It seems the problem is to do with setting a timer on a superstate. I reduced my superstate definition down to one state within the superstate and still the problem occurs. When I replace the superstate with just a normal state then no problem. This seems similar to https://jira.jboss.org/jira/browse/JBPM-2036. Will make a comment there but think this is a separate issue.
