Hi Alejandro,
Yes, it is the JBPM-2844. I had seen you move it the jBPM-4.4. :)
But the priority of this issue is not very high. I want to notice that there is a serious issue https://jira.jboss.org/jira/browse/JBPM-2794 that many people has met.
Please reference http://community.jboss.org/thread/150965 and http://community.jboss.org/thread/150555. If you have enough time, please review this, thank your very much.
