invalidJavadocTags does not consider default access modifiers

[Frettman]

invalidJavadocTags can be configured to only examine methods with certain access modifiers (invalidJavadocTagsVisibility). However this seems to only consider explicitly specified modifiers and not effective/default modifiers.

E.g. when invalidJavadocTagsVisibility is set to protected it should validate all methods in an interface since they are all implicitly public. However, a warning is only created when the method is explicitly marked as public:

public interface MyInterface
{
  // creates a warning
  /**
   * @param doesNotExist
   */
  public void test1();

  // does not create a warning
  /**
   * @param doesNotExist
   */
  void test2();
}
