Hi Rory, Thanks for all updates! we have several projects under the Hibernate umbrella, so our experience varies a bit. Let me start with the good news: both Hibernate Validator (Reference implementation of Bean Validation) and Hibernate Search (Hibernate ORM integration with Apache Lucene) seem to work just fine. We had to disable various integration tests as several other platforms and tools we use for more extensive testing aren't yet at the same level of compatibility, or possibly we need to still figure out the right combination of updates and JVM flags to get them working: we're in the process of refining that but it's not worrying as it's about running different components, our libraries work fine. Our "flagship project" Hibernate ORM seems like in good shape as well but it will still take us some time to be able to give a thourough answer, as many more essential build and testing tools are still affected by compatibility issues. So for this one we currently can't run the core testsuite which leaves us partially in the dark, but I'm optimistic as several key functional tests of the Hibernate Search testsuite indirectly rely on Hibernate ORM as well and they all work just fine. All build issues we found so far are in the "expected changes" cathegory so we're not having bugs to report to the OpenJDK; we might have to chase several of these tool maintainers. We'll keep working on this and let you know.
