Heidi Buelow, Product Manager at Oracle for BPM Suite posted a note on the Oracle Forums over the weekend asking a member to hold off on using JDeveloper 11g PS3 with BPM.

I am generally pleased with the integration, and truly appreciate the vision of using one IDE (JDeveloper) for all things Oracle. That said, it seems Oracle is unique when compared to pure-play BPM vendors where the SOA/BPM teams are different than those over development tooling like JDeveloper, so they have to work extra hard at it. Feel free to follow the forum post.
