@Override
public void handle(Invocation invocation, AsyncResponse asyncResp) throws Exception {
  if (invocation.getHandlerIndex() > 0) {
    // handlerIndex > 0, which means this handler is executed in handler chain.
    // As this flow control logic has been executed in advance, this time it should be ignored.
    invocation.next(asyncResp);
    return;
  }

  // The real executing position of this handler is no longer in handler chain, but in AbstractRestInvocation.
  // Therefore, the Invocation#next() method should not be called below.
  if (!Config.INSTANCE.isProviderEnabled()) {
    return;
  }
