Hi Yoann, Thanks a lot for the update. It looks the annotation processing heads-up was useful. 😉 --David From: Yoann Rodiere <yoann(a)hibernate.org&gt; Date: Monday, 23 October 2023 at 18:03 To: Hibernate Dev <hibernate-dev(a)lists.jboss.org&gt;, David Delabassee <david.delabassee(a)oracle.com&gt; Cc: Christian Beikov <christian.beikov(a)gmail.com&gt; Subject: [External] : Re: [hibernate-dev] JDK 21 Is Now GA, a New VS Code Extension, and an Annotation Processing Heads-up Hey David, This is to confirm that Hibernate projects work just fine with JDK 21/22: Hibernate ORM: Versions 6.3 and 6.2 tested against JDK 11 / 17 / 21 (GA) / 22 (EA 20). No problems to report. Hibernate Validator: Version 8.0 tested against JDK 11 / 17 / 21 (GA) / 22 (EA 20). No problems to report. Hibernate Search: Version 7.0 and 6.2 tested against JDK 11 / 17 / 21 (GA) / 22 (EA 20). No problems to report. Hibernate Reactive: Version 2.0 tested against JDK 11 / 17 / 21 (GA) / 22 (EA 20). No problems to report. Annotation processing changes did impact our integration tests, but Christian (CC) handled this easily, it seems.
