Minecraft Linux Don’t Work

minecraft-java-editiontechnical-issues

After I pressed the "Play" button, Minecraft crashes after about 3 seconds. Here is the message:

Does anyone know why this is happening? Thanks.

That error means Minecraft is being run with a Java version that is too old to handle the files it is given. Class version 52 corresponds to Java 8, so you'll need 8 or newer to run Minecraft. If you already have that installed, please check that it is the default. If you need to keep Java 7 or earlier as the default, it should be possible to tell the launcher to use 8, but I think we'd need to know more about your setup to help with that. If you don't need the older version(s) at all, you should be safe to uninstall them.
