Motivation: InternalAttribute doesn't extend Attribute, but its equals only returns true when it compares with an Attribute. So it will return false when comparing with itself. Modifications: Make sure InternalAttribute return false for non InternalAttribute objects. Result: InternalAttribute's equals works correctly.
