java smack openfire初始化失败?报错

最近在学习如何实用openfire来做一个消息推送服务器。学习smack的时候按照官方文档写了一个test。

但是启动的时候就报错。ExceptionInInitializerError。

官方文档上并没有找到解决方法。

以下是异常:

    根据官方的例子写的测试通过

    XMPPTCPConnectionConfigurationconfig=XMPPTCPConnectionConfiguration.builder()

    // .setUsernameAndPassword(username,password)
             .setServiceName(serviceName)
             .setHost(host)
             .setPort(5222)
             .setDebuggerEnabled(true)
             .setSecurityMode(SecurityMode.disabled)
             .build();
    //AbstractXMPPConnectionconn2=newXMPPTCPConnection(username,password,"127.0.0.1");
        AbstractXMPPConnectionconn2=newXMPPTCPConnection(config);
        try{
    //SASLAuthentication.registerSASLMechanism(newSASLPlainMechanism());
          conn2.connect();
    //conn2.login();
          conn2.login(username,password,resource);
