code: public static void initialize() {
          clear();
          threadLocal.set(new HashMap<String, Object>());
  
          // for e.g. Lasta RemoteApi-0.3.7 (depends on LastaFlute-1.0.0), deleted at future
          setObject(FW_REMOTE_API_COUNTER_INITIALIZER, remoteApiCounterInitializer);
      }
docs: Initialize this cache to be available. <br>
  You can use this cache after this initialization. <br>
  Don't forget to clear the cache in finally clause like this:
  <pre>
  try {
  {@link ThreadCacheContext#initialize()};
  ...
  } finally {
  {@link ThreadCacheContext#clear()};
  }
  </pre>
