(Note: I'm a firm believer in "if it works, you don't need to fix it." Which is why this laptop is still running Linux Mint 16 - so far it does everything I have needed, and wonderfully so.)
I had begun playing with MineCraft, and one of the plugins started behaving erratically, leaving me messages that I needed to upgrade from 7 to 8 for better compatibility. Naturally, there is NO place that makes this upgrade easy or simple. So I browsed out to the web looking for an instruction set that would enable me to accomplish this. Achieved: Wiki-How From all outward appearances it would seem that I have successfully upgraded Java.
Until I decided to start MineCraft back up. On Linux MineCraft doesn't leave a startup log on your desktop as it does on Windows, so I had to try and run the java command line at a prompt to find this error:

...everything else seems to run fine, and the important thing that I'm trying to figure out is how to fix what I busted, as surely I have busted something in my ignorant attempts to upgrade Java.
Before this becomes a "chicken-egg" argument, I carefully weighed the idea of posting this under Gaming but decided that it was my ham-fisted attempts at upgrading a major process library that caused the issue, thus I filed it under Linux, throwing myself on the mercy of the deities of same.
