Question

我们正在使用Openfire 4.1.1并尝试与smack连接，使用之前的版本4.1.9，它运行得非常好。但是为了实现XEP-0313（MAP），必须使用smack版本4.2.0-rc1进行更新。

这是XMPPTCPConnectionConfiguration，

InetAddress inetAddress = InetAddress.getByName(mServiceName);

//InetAddress inetAddress = InetAddress.getLocalHost();

XMPPTCPConnectionConfiguration xmpptcpConnectionConfiguration =
XMPPTCPConnectionConfiguration.builder()
              .setXmppDomain(mServiceName)
              .setUsernameAndPassword(mUsername, mPassword)
              .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
              .setHostAddress(inetAddress)
              .setPort(5222)
              .setDebuggerEnabled(true)
              .setSendPresence(true)
              .setDebuggerEnabled(true)
              .setCompressionEnabled(true)
              .build();

此处mServiceName是本地IP地址＆＃34;＆＃34; 192.168.X.X＆＃34;。

异常，

请检查HostAddress类构造函数。可能是因为fdqn值是＆＃34;＆＃34;。

public HostAddress(int port, InetAddress hostAddress) {
    this("", port, Collections.singletonList(hostAddress));
}
public HostAddress(String fqdn, int port, List<InetAddress> inetAddresses) {

    Objects.requireNonNull(fqdn, "FQDN is null");
    if (port < 0 || port > 65535)
        throw new IllegalArgumentException(
                "Port must be a 16-bit unsiged integer (i.e. between 0-65535. Port was: " + port);
    if (fqdn.charAt(fqdn.length() - 1) == '.') {
        this.fqdn = fqdn.substring(0, fqdn.length() - 1);
    }
    else {
        this.fqdn = fqdn;
    }
    this.port = port;
    if (inetAddresses.isEmpty()) {
        throw new IllegalArgumentException("Must provide at least one InetAddress");
    }
    this.inetAddresses = inetAddresses;
}

或者，如果我做错了什么，还有其他选择吗？原始问题is here。

这是一个应该在4.2.0-rc2中修复的错误。尝试4.2.0-rc2-SNAPSHOT直到它被释放。

Smack版本4.2.0-rc1 XMPPTCPConnectionConfiguration setHostAddress（）抛出StringIndexOutOfBoundsException
