Default methods for interface classes were invented to solve a problem of compatibility if I remember correctly. Forcing subclasses to implement the interface method or have a superclass of the subclass to implement the interface method seems like it avoids the problem of silently not registering the cleanup or action that the interface method should force you to do. To solve the duplicated registerCleanup() cases, the two other classes could extend FinalizableObject then inherit its implementation of registerCleanup(). ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/13420#discussion_r1185337107
