Upon trying to load in the MC client once dropping in Mekanism, the client crashes with the error "UnsupportedClassVersionError : mekanism/common/asm/LoadingHook : unsupported major.minor version 51.0"

I have tried multiple versions of Mekanism, including the newest release.

The full client log of the error can be found here: http://pastebin.com/aqsMhN32

@aidancbrady and @unpairedbracket just as a heads up that I don't see mentioned here, to get a Mac to properly use Java 8, users NEED the Java 8 JDK, not the JRE. Dunno why exactly this is but that's how it currently works.

Seems to have something to do with minecraft using CLI stuff and the damned apple shipped jre overrides the jre from oracle somehow. You'd think oracle would be suing apple over that.

Update Java.

I am running Java version 8 update 45…I do believe that is the absolute latest version of Java.

You may want to double check that, it seems you have Minecraft running on a Java 6 install. Check your Minecraft game profile's JVM arguments.

I’m confused…my system is on Java 8, I have just confirmed. I’m not sure what to put for the JVM arguments.
I’m using the Minecraft vanilla launcher to test a modpack that I am putting together.

I think Apple Java strikes again. Minecraft is for some reason not using the JVM you want it to. Don't know why Apple haven't updated their shipping JVM yet but I'm starting to doubt they ever will.

Yeah, seems like it.

I’m researching how to manually change the Java version the launcher uses.

They never will :(

I was able to get it working! Thank you!

P.S. sorry about filing a false bug report. I was unaware that regardless I have Java 8 installed, Minecraft was running Java 6.

Keep up the great work on Mekanism! Is there anywhere I can track what you're up to next?

Great! No worries, we get that report a lot.

You can keep up with me on Twitter or my website (aidancbrady.com), and I know @unpairedbracket has a (very aesthetically pleasing) site in the works at unpairedbracket.github.io. Glad you like Mekanism :)

Oh it’s overtaken the spot as my favorite Tech mod for sure!
Can’t wait for the next update!
