Was verursacht dieses Problem?

If you want to edit an interface:
After the interface was transported, changes to the interface are
always incompatible, either for the caller of interface methods (when
you change or delete components), or for the classes that implement the
interface (any changes).

Wie behebe ich diesen Fehler?

If you want to edit an interface:
When the class is not yet final and the interface was already
transported, changes to the interface are always incompatible, either
for the calling program (when you change or delete components), or for
subclasses (when you add or delete public or protected components)

Wie behebe ich diesen Fehler?

Consider whether the planned changes are really necessary. After you
have changed the interface, make sure that you inform those responsible
for the classes that implement or inherit it, since these classes can
be syntactically incorrect as a result of your changes.
