/**
 * Pushes the given span onto the {@link #currentSpanStackThreadLocal} stack. If the stack is null it will create a new one. Also pushes the span info into the logging
 * {@link org.slf4j.MDC} so it is available there.
 */
protected void pushSpanOntoCurrentSpanStack(Span pushMe) {
  Deque<Span> currentStack = currentSpanStackThreadLocal.get();
  if (currentStack == null) {
    currentStack = new LinkedList<>();
    currentSpanStackThreadLocal.set(currentStack);
  }
  currentStack.push(pushMe);
  configureMDC(pushMe);
  classLogger.debug("** starting sample for span {}", serializeSpanToDesiredStringRepresentation(pushMe));
}

/**
 * Completes the current child sub-span by calling {@link #completeAndLogSpan(Span, boolean)} on it and then {@link #configureMDC(Span)} on the sub-span's parent
 * (which becomes the new current span).
 * <p/>
 * <b>WARNING:</b> This only works if there are at least 2 spans in the {@link #currentSpanStackThreadLocal} stack - one for the child sub-span and one for the parent span.
 * If you're trying to complete the overall request's span you should be calling {@link #completeRequestSpan()} instead. If there are 0 or 1 spans on the stack then
 * this method will log an error and do nothing.
