As a result, objects previously stored as valid profiles may now throw an IllegalArgumentException during serialization. Discussion about serialization was started in https://github.com/openjdk/jdk/pull/23044 but it seems at the end non-serialization related check was [verified](https://github.com/openjdk/jdk/pull/23044/commits/a5201b5f353e8957a1274261372496768edbc7a2). =(

Initial review LGTM. 

As @prrace mentioned here https://github.com/openjdk/jdk/pull/27326#discussion_r2356533149, the closed tests need to be updated. Probably requires coordinated integration of open + closed PRs.
