The following produces an error and a warning. The warning is redundant.

public class StaticInvoke {

  interface I {
    static void m() { m(); } // ok
  }
  
  void test(I arg) {
    I.m(); // ok
    arg.m(); // error
  }
}

StaticInvoke.java:9: warning: [static] static method should be qualified by type name, I, instead of by an expression
    arg.m(); // error
       ^
StaticInvoke.java:9: error: illegal static interface method call
    arg.m(); // error
         ^
  the receiver expression should be replaced with the type qualifier 'I'
