Description

Currently, the incr/decr operation on the ref count of HConnectionImplementation are not atomic. This may cause that the ref count always be larger than 0 and the connection never be closed.

    /**
     * Increment this client's reference count.
     */
    void incCount() {
      ++refCount;
    }

    /**
     * Decrement this client's reference count.
     */
    void decCount() {
      if (refCount > 0) {
        --refCount;
      }
    }
