Whenever I try to run this at all, It always gives me a "Socket Timeout! Is the server offline?" regardless of the IP address and port entered in.
Full error: Socket Timeout! Is the server offline? Exception in thread "main" java.lang.NullPointerException: Cannot read the array length because "bytes" is null at java.base/java.lang.String.<init>(String.java:632) at query.MCQuery.handshake(MCQuery.java:45) at query.MCQuery.basicStat(MCQuery.java:54) at mainStuff.testerewr.main(yepThisIsABucket.java:8)

There is a bug in this API if you start the Minecraft server with

motd=\u00A7e<\u0000

In the QueryResponse.java there is
motd = new String(temp[3]);

but when you put this strange motd the temp[4] is empty and then all others variable attribution are wrong.

To produce the bug just put motd=\u00A7e<\u0000 in your server.properties file and start the server. Then try to get the full Query info.

code

package com.themixray;

import java.util.logging.Logger;

public class Main {

    public static void main(String[] args) {
        Logger log = Logger.getLogger("LOG");
        long st = System.currentTimeMillis();
        MCQuery mcQuery = new MCQuery("0.tcp.ngrok.io", 12601);
        QueryResponse response = mcQuery.basicStat();
        float ping = (float)System.currentTimeMillis()-st;
        log.info("ping "+Float.toString(ping));
    }
}

I get a NullPointerExeption with this "token = Integer.parseInt(new String(result).trim());" on line 45 in class MCQuery.

If there is a single quote in a JSON string, it won't parse properly. This occurs sometimes when there is a single quote in a server motd string.

Is there a jar file or anything I have to put in my build.gradle?
or do I have to build it myself?
