JDK 17 delivered JEP 409: Sealed Classes : https://openjdk.java.net/jeps/409 In essence this JEP allows a class to limit which classes can subclass it.
Path2D can be sealed because no code outside the package can sub-class it directly. However the extant subclasses need to be made non-sealed as they can be sub-classed. jtreg tests and JCK API tests pass.
