RedundantModifier

Checks that method declarations in interfaces include neither the public modifier nor the abstract modifier (see the Java Language specification, section 9.4).

Also checks that variable declarations in interfaces include none of the following modifiers: public, static, final (variables in interface definitions are constants and have these modifiers implicitly, see the Java Language specification, section 9.3).
