Hi, There were lots of differences in the compatibility report, so as a first step, I've excluded packages/classes that I considered SPI, internal, or "grey area". This reduced the the differences to a more manageable amount.
You can see a summary of the incompatibilities along with suggested mitigation at [1]. The report is attached to [1], along with a zip with instructions for running the report. I believe there are some "false positives" in the report, and I have documented them in the section, "False Positives?". Feel free to comment on the article. Thanks, Gail [1] https://developer.jboss.org/wiki/HibernateORMBinaryCompatibilityBetween51And53 _______________________________________________ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
