If you’ve recently updated to Minecraft 1.18, and now you’re seeing the error ‘a JNI error has occurred’, you may need to update your Java software. This can be done by downloading the latest Java version from the official website and installing it directly on your PC. Once downloaded, extract the file with an extracting tool and paste it in the C:/Program Files/Java folder. This should fix the problem.
Another possible cause of this error is a mismatch between the Java version on your computer and the version of the game you’re using. If your computer is running Java 8 or earlier, this error will occur when you try to launch Minecraft or launch a server. The latest Java version is 16.
There are a few ways to fix the error. First, check your Java installation path. Make sure you’ve selected the correct version. If you have updated the version of Java, you should have a clean installation. If you’ve had issues in the past, you might need to reinstall the game.
The JNI error in Minecraft is caused when the game can’t load native files. Usually this occurs because you have an outdated version of Java or a damaged or missing Java 16 JDK file. A broken path may also be a cause, or a third-party application may be interfering with the game.
Another solution is to uninstall your security software. Third-party antivirus programs can interfere with other programs. Some antivirus software can prevent the game from running and downloading updates. Therefore, if you’re experiencing the error, uninstall the security software and then launch the game again. Then, you’ll see if the JNI error is gone.
If you’re unable to fix the error, you can contact your server hosting company. You can also update your Java version. This can be done by accessing your system’s Properties screen and removing the Java PATH environment. This should resolve the error.
If you’re running a Minecraft server, you can also check the server’s logs for errors. There may be many reasons why the server is experiencing the jni error. One possible cause is a conflict with your mods. Sometimes, your server may be downgrading to an older version, and this will affect your server’s functionality.
