    posted a message on [StoneBlock] Immediately crashes after starting

    This is my first time using the Twitch Launcher.  I am trying to play the StoneBlock, but whenever I hit Play on the Minecraft instance, it immediately crashes and pops up with this

    Exception in thread "main" java.lang.UnsupportedClassVersionError: joptsimple/OptionSpec : Unsupported major.minor version 51.0

    I have tried updating Java, restarting the Minecraft instance, restarting the Twitch launcher, restarting my computer, and deleting & re-downloading the mod pack, but nothing seems to work.

    I am doing this on my Mac, so I don't know if that is affecting it
