Many companies I've seen in Mexico are very reluctant to migrate their stable applications to a new app server or a new JVM. I know a bank that was using WAS 3.5 two years ago, just to make my point. So, I think that jBPM having a dependency on J2SE 5.0 would not be such a good idea. So far, I don't know a single big company that's using J2SE 5 on a daily basis. Regards.
