            <title>[MC-6941] SRV is no longer used to lookup servers</title>
                <link>https://bugs.mojang.com/browse/MC-6941</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;The client is not using the SRV record to lookup the server it connects to.&lt;/p&gt;

&lt;p&gt;Both the ping in the multiplayer menu and the direct connect fail.&lt;/p&gt;

&lt;p&gt;I sniffed the DNS packets and found that only A and AAAA queries were made.&lt;/p&gt;</description>

&lt;div class=&quot;code panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;codeContent panelContent&quot;&gt;
&lt;pre class=&quot;code-java&quot;&gt;$ sudo tcpdump -vvv -s 0 -l -n port 53`
&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;

&lt;p&gt;Not a single SRV query was made, A queries only, even after the A queries returned NXDOMAIN.&lt;/p&gt;

&lt;p&gt;Java version:&lt;/p&gt;
&lt;div class=&quot;code panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;codeContent panelContent&quot;&gt;

                            <comment id="62917" author="root" created="Tue, 23 Apr 2013 23:55:09 +0200"  >&lt;p&gt;The issue is not fixed at all. The (vanilla) Minecraft client does not query the DNS recursor for SRV records.&lt;br/&gt;
A look at the DNS queries (using Wireshark) shows that the current Minecraft client only queries for AAAA- and A-records but not for SRV-records.&lt;/p&gt;

&lt;p&gt;Mojang, please fix it finally!&lt;/p&gt;


&lt;p&gt;Technical details:&lt;/p&gt;

&lt;p&gt;Minecraft version: 1.5.1&lt;br/&gt;
Oracle JRE version: 1.7.0_21 (x64)&lt;br/&gt;
Operating system: Ubuntu 10.04 x64&lt;/p&gt;

&lt;p&gt;$ dig +short SRV _minecraft._tcp.whatevercraft.com&lt;br/&gt;
0 5 25565 server.whatevercraft.com.&lt;br/&gt;
$ dig +short A server.whatevercraft.com&lt;br/&gt;

&lt;p&gt;Versions installed are (from control panel, add/remove programs):&lt;/p&gt;

&lt;p&gt;Java 7 Update 7 (64 bit) - version 7.0.70&lt;br/&gt;
Java 7 update 11 - version 7.0.110&lt;br/&gt;
Java SE Development Kit 7 Update 7 (64-bit) - ver 1.7.0.70&lt;/p&gt;

&lt;p&gt;From the Minecraft snooper settings page, the java_version value is 1.7.0_07&lt;/p&gt;</comment>
                            <comment id="40685" author="grum" created="Mon, 28 Jan 2013 16:41:17 +0100"  >&lt;p&gt;The SVR lookup was done using sun.* classes and would give huge timeouts for people who didn&apos;t use the Sun JRE. Now we check for the existance of the class used before we do the SVR lookup to prevent that. From this I can only assume you do not have that class and thus are not using Sun&apos;s JRE.&lt;/p&gt;

&lt;p&gt;If you stumble upon a better way to do the SVR lookups feel free to let us know.&lt;/p&gt;</comment>
