Luis Blando wrote his Master's thesis a few years ago 
on this topic. He called the extended interfaces: personalities.

It is very nice to have support for personalities in AspectJ and
the design issues addressed in the personalities work
are also relevant to AspectJ users.

Good news.

...

--mixins--

The third kind of change is a decision to be more direct about the way
in which AspectJ adds multiple-inheritance to Java.

Many have noticed that AspectJ adds mixin-inheritance like behavior to
Java through its ability to introduce non-abstract methods onto
interfaces.

To simplify the behavior of introduce, and to make this inheritance
behavior somewhat cleaner, we will now allow methods with bodies to
appear in interface declarations.
