Hi, Vladislav! As I mentioned before, we already have some failures on JDK 17. One more example is the Binary Objects (Simple Mapper Basic) suite [0]. It is almost green on JDK 11, but consistently red with the JDK 17 tag. Also, as far as I can tell, we do not yet have comparable statistics for JDK 21. So it probably makes sense to first fix the known JDK 17 issues to minimize migration risks, and then move to JDK 17 while running nightly builds on JDK 21 in parallel. What do you think?
