&lt;p&gt;Can someone explain what the &apos;ns&apos; class is.&lt;/p&gt;

&lt;p&gt;I was playing around with the new features and it came apparent that, under any difficulty; Zombies, skeletons, creepers, Zombie Pigmen, Witches, Ocelots, and Wolfs will not spawn from mob eggs and in the dark. After about 10-15 seconds after attempting to spawn these mobs the game crashes&lt;/p&gt;

&lt;p&gt;**&lt;b&gt;UPDATE!!!&lt;/b&gt;**&lt;/p&gt;

&lt;p&gt;Ok, so I have updated my Java, and minecraft no longer crashes once spawning these mobs, however they still do not spawn, please see the video in the comments for a demonstration. Thanks&lt;/p&gt;</description>
