What Kind of Error Is the Minecraft JNI Error?Minecraft JNI Error The “a JNI error has occurred” in Minecraft is only found in the Java versions of the game. It basically means that the game or the server you’re trying to join has a Java-related issue. Unfortunately, fixing the Minecraft JNI error doesn’t have a simple fix. While you should try restarting the game and restarting your computer, it’ll most likely not resolve the issue as it would with exit code 1 or error code 502. That said, there are a couple of more advanced solutions that shouldn’t take too much time and will surely fix the Minecraft JNI error. Install the Latest Java VersionThe first thing you should do is install the latest Java version. While you could download the JRE version, it’s better to download the JDK one, especially if you’re running a server or mods. All you need to do is choose your desired version (I’d suggest you pick the latest one), and download the installer. Then, follow the instructions on the installation tab, and you should be able to play Minecraft again. Update your Minecraft modsThe JNI error can sometimes be related to your Minecraft mods. So, make sure that each mod is updated, especially if you’re running on a new Minecraft version. Delete Broken Java System VariablesIf none of the above has helped you fix the Minecraft JNI error, you’ll need to check your “System Variables”. There are a few steps that you’ll have to follow for this, though:
Using the Run command to find the System variables
Selecting the Environment Variables
Finding the javapath issue
Deleting the javapath variables
After that, the JNI error should be fixed! ConclusionHopefully, this has helped you fix the Minecraft JNI error, and you can hop on your favorite server again.
