Hey David, Best wishes for the new year! Better late than never: this is to confirm that Hibernate projects work just fine with JDK 22 (EA 28) / 23 (EA 2). Hibernate ORM: Version 6.2 tested against JDK 11 / 17 / 21 / 22 (EA 28), version 6.4 tested against the same and also JDK 23 (EA 2). No problems to report. Hibernate Validator: Version 8.0 tested against JDK 11 / 17 / 21 / 22 (EA 28) / 23 (EA 2). No problems to report. Hibernate Search: Version 7.0 tested against JDK 11 / 17 / 21 / 22 (EA 28), version 7.1 tested against the same and also JDK 23 (EA 2). No problems to report. Hibernate Reactive: Version 2.2 tested against JDK 11 / 17 / 21 / 22 (EA 28) / 23 (EA 2). No problems to report. I also confirm that the bug we reported some time ago (JDK-8321164 [1]) was indeed fixed as the Hibernate ORM annotation processor tests pass once again with JDK 22.
