About this Mod

This mod is intended to be used by Mod Packs. If a user tries to launch the game with an outdated version of Java they will be given a warning. This warning will direct them on how they can update the game or allow them to ignore the warning completely. By default Twitch and Mojang will use Java version 1.8.0_51 which has various performance and security issues that can cause issues with newer mods. This mod can also warn players who have installed Java 32 bit on a Java 64 bit system, which can also cause many issues.

The warning message includes three options for players.

Read More: Opens up a link to info on how to update.
Ignore: Closes the warning. It will be shown again on the next launch.
Stop Reminding: Disables the mod and it's warning.
