Beware of the BUG !

Had an issue today with an exception that blew up minecraft.

Looks a bit like:

Caused by: java.lang.IndexOutOfBoundsException
 at java.nio.Buffer.checkIndex(Buffer.java:512) ~[?:1.6.0_65]
 at java.nio.DirectIntBufferU.get(DirectIntBufferU.java:248) ~[?:1.6.0_65]
 at net.minecraft.client.renderer.RenderGlobal.func_72712_a(RenderGlobal.java:386) ~[bls.class:?]

Turns out its associated with:
https://bugs.mojang.com/browse/MC-38527

… just follow the moderators note to fix.
