Overriding default methods in interfaces reported as binary incompatible.

[jake-at-work]

I am confused as to why overriding the methods from one interface in another between releases is detected as a binary incompatible change.

I am trying to deprecate methods inherited by poor choices in inheritance so that we avoid implementations using those methods and can later drop the bad inheritance.

Effectively we are going from this:

interface Something extends SomethingElse {
    default void doSomething() {}
}

interface SomethingElse {
    default void doSomethingElse() {}
}

to:

interface Something extends SomethingElse {
    default void doSomething() {}
    @Deprecated
    @Override
    default void doSomethingElse() {}
    default void doSomethingBetter() { doSomethingElse(); }
}

interface SomethingElse {
    default void doSomethingElse() {}
}

It is reported as: Error	Class Something: Is not binary compatible
Error	Method Something.close(): Is not binary compatible METHOD_NEW_DEFAULT
Error	Method Something.doSomethingBetter(): Is not binary compatible METHOD_NEW_DEFAULT
Error	Method Something.doSomethingElse(): Is not binary compatible METHOD_NEW_DEFAULT ANNOTATION_DEPRECATED_ADDED

I would appreciate any insight into this issue and how best to deal with it.
