This is a really good question, I appreciate you asking this.
I usually suggest to report the issue, in Jira you can select the affected version and the developers will choose the version in which the bug or the feature request will be included.
In order to create an Issue you should have a jira account and inside it you can select the project, in this case jBPM.
Thank you Mauricio, I'll do as you suggest.
I've been working my way through your book and blogs - it's nice to be able to say hello!
I appreciate your comments on the book and blog! I'm looking forward to start writing again about the new stuff that we are creating now.
Let's stay in touch, if you have more issues or suggestion please let us know.
