Yes. We have to "foreport" the join solution from jBPM 3.2.9 (see  https://jira.jboss.org/browse/JBPM-2790 JBPM-2790) to jBPM 4.4. For the time being, try setting the  http://docs.jboss.com/jbpm/v4/userguide/html_single/#asynchronouscontinuations continue attribute to async or exclusive in the join activity in order to reduce the window of opportunity for a locking conflict.
