Scott,
To me, jBPM 5 looks a lot more like Drools Flow than jBPM 4.x: for
example, the vision includes WS-HT, integrated rules/events, and
apparently no support for jpdl.
Part of these decision are driven by the fact that we acknowledge the
importance of standards instead of custom, proprietary solutions. I
think the user will only benefit from using a standard in the long run.
These decisions have been discussed internally for quite some time as
part of a consolidation effort and most of these decision have been
agreed on with both teams a long ago. Imho, they are the normal next
step forward, not a move away from the existing jBPM vision.
