I think that there are two different ideas / thoughts in here: (a) JDK / JRE 17 Runtime: Be able to deploy and operate a TomEE with a Java 17 environment. This might be solvable by adding JVM options (as mentioned by Thiago and Vicente) or doing some rework of the proxy factory (looks like a solution without the JVM flags as mentioned by Jon)
(b) _Compiling_ TomEE with JDK 11+ For (b) and Corba: I had worked on it a in 2020 and had two drafts. In May, we had some issues with a force push to master, which closed / killed all open PRs, which render the diff nearly useless. The drafts: - https://github.com/apache/tomee/pull/713 (use byte code generation at build time -> drawbacks as mentioned by Romain) - https://github.com/apache/tomee/pull/792 (using SPI to lookup a corba integration module, which can be compiled with Java 8 and is not included in the main tomee project. I guess it would require some cleanup / update and the open tasks adressed. PR 721 had some open questions, which I couldn't resolve at the time it was created. It might be worth to pick up the work on a J11+ build. The mail discussion is located here [1].
