Hi, WildFly 18 supports JDK 13, so Hibernate ORM 5.3.12 will also need to support JDK 13. We know that ByteBuddy needs to be upgraded to 1.9.11. That will be covered by HHH-13504 [1] Andrea mentioned HHH-13415 [2] should be backported as well. Grepping through the log for jdk, I see these other issues that were resolved in master, but not 5.3: https://hibernate.atlassian.net/browse/HHH-12946 https://hibernate.atlassian.net/browse/HHH-13022 https://hibernate.atlassian.net/browse/HHH-13069 https://hibernate.atlassian.net/browse/HHH-13043 https://hibernate.atlassian.net/browse/HHH-13128 https://hibernate.atlassian.net/browse/HHH-13127 https://hibernate.atlassian.net/browse/HHH-13271 https://hibernate.atlassian.net/browse/HHH-13275 https://hibernate.atlassian.net/browse/HHH-13419 https://hibernate.atlassian.net/browse/HHH-13421 https://hibernate.atlassian.net/browse/HHH-13409 Did I miss anything? Could someone please determine which of these need to be backported? Better yet, could someone please create a pull request for 5.3? I specifically need to know about any component upgrades that will be required besides ByteBuddy, so I can clear it with WildFly folks. I need to get 5.3.12 released in the next couple of days at the latest. I am aiming for tomorrow, but I'm really not sure what it would entail for Hibernate ORM 5.3 to support JDK 13. Help would be very much appreciated. Thanks! Gail [1] https://hibernate.atlassian.net/browse/HHH-13504 [2] https://hibernate.atlassian.net/browse/HHH-13415
