And it seems to be an issue between Tycho JDT and JDK17. mvn -X shows nice parameters were passed to JDT but I didn't look into it. I will try to see what happens when switching the tycho compiler to javac. Don't know whether that's possible/a good idea...

Yup, you're right. I figured that out. I guess we have to live with the workaround. We can try once again with tycho 2.6.0 which should be out really soon. But if that doesn't change a thing we can only open an issue with tycho.
