            <title>[MC-5085] NullPointerException on connection</title>
                <link>https://bugs.mojang.com/browse/MC-5085</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;After upgrading to 1.4.6 there was about 5 minutes of successful gameplay, and then all players were disconnected after the server reported NullPointerException stack traces.&lt;/p&gt;

&lt;p&gt;Subsequent attempts to connect are all unsuccessful. The server console reports:&lt;/p&gt;

&lt;p&gt;2012-12-20 16:48:04 &lt;span class=&quot;error&quot;&gt;&amp;#91;INFO&amp;#93;&lt;/span&gt; Gangoggs&lt;span class=&quot;error&quot;&gt;&amp;#91;/10.0.1.7:63961&amp;#93;&lt;/span&gt; logged in with entity id 142 at (-44.30000001192093, 87.0, 335.66222514255367)&lt;br/&gt;

&lt;p&gt;This user was in creative mode. Another user in survival mode elicited the same response. The stack trace is identical on both operating systems (Linux and OSX).&lt;/p&gt;</description>
