There's nothing more frustrating than trying to get Minecraft to work when you just want to play. When Minecraft's just not working, an error message will often pop up that gives you a clue concerning what's wrong. Here's the quick fix to get Minecraft up and running again after getting a JNI Error.

Why does JNI Error happen in Minecraft?

The most common reason you'll see the message in Minecraft that says "A JNI Error Has Occurred" is that your Java software is running on an outdated version. This happens because as Minecraft is continuously updated by developers, the game is also updated with newer versions of Java. When you have an older version of Java installed, your game is no longer compatible with your installed software.
