Why would a static inner interface be used in Java?

static

I have just found a static inner interface in our code-base.

class Foo {
    public static interface Bar {
        /* snip */
    }
    /* snip */
}

I have never seen this before. The original developer is out of reach. Therefore I have to ask SO:

What are the semantics behind a static interface? What would change, if I remove the static? Why would anyone do this?
