First, there is 2 days of JUDCon, May 2 - 3. JUDCon is an event by developers, for developers. I attended JUDCon Berlin last year and it is a great place for developers to learn the details of different technologies and meet the core developers and other community developers out there. Presentations will include a range of deep technical dives into JBoss Community projects and related technical topics of developer interest. And the hack fests allow you to do some real coding as well.
There are a handful of jBPM-related presentations, and many many more. Check out the agenda and register today!
