We are currently using jBPM 4.4 (actually it's the unreleased revision 6879, as it contains a feature that is needed by our implementation) which is integrated in our own frameworks. I havea process definition with nested fork/joins. The joins have a multiplicitygiven. When I finish a nested fork/join (multiplicity=2), the parallel executions of the enclosing fork/join are also finished. See the example screenshots below. 

Screenshot 1 shows the execution of the workflow before a nested fork/join is finished. This is actually done by completing the human Task +PC Hard- / Software bestimmen+ (right-most task that is bordered with the color red) in the screenshot. After finishing this task, the nested fork/join is completed and the task +Bestehende Hardware zum Neuaufsetzen bringen+ is selected correctly (the only red-bordered Task in screenshot 2). However, the other human tasks from the enclosing fork/join are complete, although they should not.

Is there something wrong with the modeling or is this a problem within jBPM 4.4 (unreleased revision 6879)? I found the Jira issue  https://issues.jboss.org/browse/JBPM-2720?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel https://issues.jboss.org/browse/JBPM-2720?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel which may be related with this problem.

Any help is appreciated. Thanx.
