The Class-File API models a few non-standard attributes used by the JDK. They are not part of the Java SE and should not be modeled by Java SE APIs. We should remove these APIs.

Since JDK 25 is in RDP1, we probably cannot get a replacement API in time for them in 25; however, given Class-File API is designed with custom attribute support, it should be possible for users in need to define their custom attributes that handle these JDK attributes.
