Also makes more sense to use override in case we support default methods in
interfaces (Java 8) at some point.

One can open an enhancement request for this, but this issue report is invalid.

That's precisely what I was doing when I stumbled upon this, changing a
abstract class to a interface. I'm not sure why both are allowed, even though
it does no harm to keep both, it seems one should be the right way and the
other a warning possibly?

I would tend to think this is allowed.  Imagine if you switched an interface to
an abstract base class or vice versa, you wish to make someone go through all
their calls and add/remove override?

I had a bug fixed a long time ago, issue 2524.

In a comment, Walter said:

"This is a compiler bug. You can override an interface function."

I'm assuming this still applies today.
