How to Fix Minecraft JNI Error Has Occurred

On June 8, 2021, the latest version of Minecraft was finally made available to players. The update, called Caves & Cliffs, adds new mobs like goats, glow squids, and axolotls, as well as new things that can be mined, like copper ore. The patch came out for the version of Minecraft that runs on Java. Many users were eager to jump into the updated sandbox world, but others were very upset because they couldn’t because of an unexpected error:

“A JNI error has occurred, please check your installation and try again,” which was often followed by “A Java Exception has occurred.” When Minecraft version 1.17 came out, this started to happen. Many users have said that the error happens when the TLauncher is used to start the game. It’s odd, since the message says that the version of Java is broken or missing. In fact, many players who got the error said they already had Java installed on their computers.

Tech news says that the problem is with the version of Java. With the latest patch, Minecraft has been updated to use Java 16. Mojang Studios, the company that made Minecraft, says that the error happens when people try to start the video game or the server (.jar) without Java 16. we’ll show you how to try different ways to Fix Minecraft JNI Error Has Occurred.

Why does the JNI Error occur

The server software in older versions of Minecraft was compatible with older versions of Java. But this wasn’t true before the latest update to Minecraft, which now needs Java to start up and run correctly. Players can avoid JNI errors by downloading and installing the latest version of Java.

Mojang has updated their version of Java as of the Minecraft 1.17 update. This means that the game could run on Java 8 until Minecraft 1.16. But as of version 1.17, the game can only be played on Java 16 or higher (the latest versions). This would cause the JNI Error to happen when you tried to run your Minecraft Server. The cause is that the Java version doesn’t match, and if you do these steps, the game should run correctly.

Java 18 and later is easy to download and install, and when you start the download process, you will be shown what to do. If this fix changes in any way or if there is another error like JNI, we will cover it as soon as possible. You can now download, install, and play your favorite game without any problems.
