Solved Weird error.

Hello,

I've created a plugin for a friend. He tried to install the plugin on his server but he received a weird error.
Error: https://gist.github.com/anonymous/6e4e23b2b846d7c72b7b

I've never seen this error before and I've searched it on google and they say that the plugin version doesn't support the server version.

How do I fix this?

Thanks,

You've exported your plugin with java jre/sdk 1.7 and he have is server running on java 1.8
Or inverse

 

If he exported it as Java 7 and it's running Java 8, it's compatible,
But if he exported it as Java 8 and he's using Java 7 it's not.

 

Thanks for the replies!

How can I fix this?
