Buggy source:

Fixed version (ground truth):
@Override public void before(Object target,Object[] args){
  if (isDebug) {
    logger.beforeInterceptor(target,args);
  }
  Trace trace=traceContext.currentRawTraceObject();
  if (trace == null) {
    return;
  }
  HttpURLConnection request=(HttpURLConnection)target;
  boolean connected=((ConnectedGetter)target)._$PINPOINT$_isConnected();
  boolean connecting=(target instanceof ConnectingGetter) && ((ConnectingGetter)target)._$PINPOINT$_isConnecting();
  if (connected || connecting) {
    return;
  }
  final boolean sampling=trace.canSampled();
  if (!sampling) {
    request.setRequestProperty(Header.HTTP_SAMPLED.toString(),SamplingFlagUtils.SAMPLING_RATE_FALSE);
    return;
  }
