has exactly one abstract method.  Since default methods are not abstract, any default methods declared in an interface do not contribute to its abstract method count.  If an interface declares a method overriding one of the public methods of java.lang.Object, that also does <em>not</em> count toward the abstract method count.

This is pretty murky. This works:

interface Foo {

  @Override

  boolean equals(Object other);

}

but if you try this

interface Foo {

  @Override

  default boolean equals(Object other) {

    return false;

  }

}

it does give an error that says I can't override:

java: default method equals in interface spullara.Foo overrides a member of java.lang.Object

Seems like "override" is the wrong word to use and will likely be confusing since we are explicitly disallowing the second one.
