I'm getting an error message saying my Java version is out-of-date, but I have Java 8 installed. What does this mean?
If you have multiple versions of Java installed on your system, make sure that Minecraft is using your Java 8 installation (this can be modified by the "Executable" setting in your profile settings). Alternatively, uninstall all of your older Java versions to force Minecraft to use Java 8.
