I don't change much. I just replaced this try/catch by several others.

I think this is unhelpful. Message doesn't have a readable toString representation

[wu-sheng]

This is a proto object. Isn't it output the data? I read this from decompiling codes.

  @Override
  public final String toString() {
    return TextFormat.printer().printToString(this);
  }

[wu-sheng]

For safety, I run the demo codes locally

public static void main(String[] args) {
        RemoteMessage obj = RemoteMessage.newBuilder()
                                             .setNextWorkerName("dbc").build();
        System.out.println("Default toString(): " + obj.toString());
        System.out.println("TextFormat: " + TextFormat.printer().printToString(obj));

        try {
            System.out.println("JsonFormat: " + JsonFormat.printer().print(obj));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Default toString(): nextWorkerName: "dbc"

TextFormat: nextWorkerName: "dbc"

JsonFormat: {
  "nextWorkerName": "dbc"
}
