Smack 4.2 및 CCS (XMPP에서 FCM/GCM) - Smack에서 잘못 구문 분석 된 응답 - JSON 페이로드가 삭제됩니다.

Question

Smack 라이브러리 버전 4.2는 FCM에서 보낸 것처럼 메시지 본문을 삭제하는 것으로 보입니다. 그러나

<message><data:gcm xmlns:data="google:mobile:data">{"message_type":"nack","from":"xxx","message_id":"aaaa1","error":"BAD_REGISTRATION","error_description":""}</data:gcm></message> 

, 헤로인 4.2이 메시지를 구문 분석 할 때, 그것은 메시지 내부의 JSON 본문을 삭제하고 내 패킷 수신기에 다음 날 제공 : 내가 디버거를 설정하면 , 나는 다음과 같은 수신 메시지를 볼 수 있습니다

     } 
     Thread.sleep(1000000); 
    } 
} 

내가 잘못 뭐하는 거지 :

<message><gcm xmlns="google:mobile:data"></gcm></message> 

여기 내 테스트 클래스입니까?
