Suspected incorrect check of methods from more complex interface inheritance chains

interface A {
  @WebMethod("some-method")
  void someMethod(StaplerRequest req, StaplerResponse rsp);
}

interface B extends A {
  ...
}

public class C implements B {
  public void someMethod(StaplerRequest req, StaplerResponse rsp) {
    ...
  }
}

Then C.class.getInterfaces() will include B.class but not A.class
