    // NOTE: Not sure why this test suggests that IndexOutOfBoundsException
    // should not appear due to compatibility with some buggy behavior.
    //
    // Here's the expected behavior: documentation for an exception X is never
    // inherited by an overrider unless it "pulls" it by either (or both)
    // of these:
    //
    //   * tag:
    //       @throws X {@inheritDoc}
    //   * clause:
    //       throws ..., X,...
    //
    // Neither of those are applicable here. Even taking into account
    // mechanisms such as the one introduced in 4947455, neither of
    // NullPointerException and IndexOutOfBoundsException is a subclass
    // of the other.
    //
    // So, IndexOutOfBoundsException should not appear in Extender.
