Unsupported Class Version Error

[Porterwake]

I have completely uninstalled all versions of Java and reinstalled the latest version from Oracles website and I still get the same error message.

I don't understand, this game worked for me just fine up until last week.

I don't know what happened between last week and when I got back from vacation.

I don't understand, this game worked for me just fine up until last week.

That is because the client now requires Java 8, due to the recent optimizations. Prior to that, it only required Java 5.

I can't say I know how or why your system runs some version of Java prior to 8, though, but the error message does make it clear that that is what happens. If you want to debug it further, you can open a Command Prompt or Terminal Emulator or however it is Apple names it, running the following commands and posting the output of them:

Code: Select all

java -version
ls -l $(which -a java javaws)

I am unfortunately using the MacBook Pro that I am issued from the school I teach at.

You might check with whomever does the tech support for your computers about this. They might be able to walk you through it or help you.

@loftar: could it be anything to do with Apple's wonky Java that has been a problem in the past? Or is that not an issue anymore?

I've no idea what you've managed to do here. Have you copy-pasted the command prompt into the command-prompt itself... and then added the commands I gave you to that...?

I see what stupid thing I did. I will fix it.

Thank you Loftar for your time and effort in my problem.

I believe that is what you may be looking for?

I have installed the dev kit, here is my error:

Well, that does indeed tell you, at least, that you are infact running Java 6, not Java 8. (Java 1.6 is also known as Java 6, and Java 1.8 and Java 8 -- the initial 1 is often dropped.)

I can't say I know how Java installation works on OSX, but are you really sure you followed the correct installation procedures when you downloaded Java 8?

Code: Select all

/System/Library/Frameworks/JavaVM.framework/Versions/

Are there several versions installed in this directory?

[Porterwake]

It is a directory and if you look at my recent posts, the Mac is recognizing that I am now using Java 8
