When we compile our classes with java 20 compliance, deployment fails an we get a bunch of errors saying "Unsupported class file major version 64".
When we lower the compliance to java 19 eclsipelink works fine but whe still see errors during deployment, for example :
[EL Warning]: metadata: 2023-06-13 09:31:36.926--ServerSession(732157093)--The javax.swing.event.ChangeListener class was compiled with an unsupported JDK. Report this error to the EclipseLink open source project.
java.lang.IllegalArgumentException: Unsupported class file major version 64
I did not test Eclipselink 4 yet because there ist still this eror pending in Jaxb concerning @XMLId and Inheritance so we can't use it anyway.

Do you plan to bring on a version of eclipselink 3 that supprts java 20? If not we will be in big trouble
