SonarCloud instance reports the bug here:
  Identical sub-expressions on both sides of operator "||".

bool DebugInformationRecorder::recorders_frozen() {
  return _oop_recorder->is_complete() || _oop_recorder->is_complete();
}

It seems to be this way since JDK-6964458. I don't see why it is this way. I think the intent was to check and freeze these two recorders:

class OopRecorder : public ResourceObj {
 private:
  ValueRecorder<jobject>      _oops;
  ValueRecorder<Metadata*>    _metadata;

...but they are in OopRecorder already, and so we already get what we want with a single call:

#ifdef ASSERT
  bool is_complete() {
    assert(_oops.is_complete() == _metadata.is_complete(), "must agree");
    return _oops.is_complete();
  }
#endif
