Hello Raphael, we are currently discussing creating an unified set of
BPM annotations which can drive both jBPM and Drools-Flow
implementations. What has been checked in so far might change soon :)
but I am currently moving forward with it and testing it until a
decision has been made on the unified annotation set. Will update
JBSEAM-4260 as soon as anything concrete comes out .
Thanks.
