What is JNI Error in Minecraft?

JNI stands for Java Native Interface, which is a programming framework that allows Java applications to call native code. The JNI error in Minecraft occurs when the game tries to access a native library that is either missing or corrupted. This error can occur for several reasons, such as outdated or incompatible software, missing or corrupted files, or conflicts with other programs running on your computer.

Common Causes of the JNI Error in Minecraft

There are several reasons why the JNI error may occur in Minecraft. Here are some of the most common causes:

  1. Outdated or incompatible software: Minecraft requires the latest version of Java to run smoothly. If you have an outdated version of Java or incompatible software installed on your computer, it can cause a JNI error.
  2. Missing or corrupted files: If the Minecraft installation files are missing or corrupted, it can cause a JNI error. This can happen due to an incomplete or interrupted installation process, or if the files have been deleted or modified.
  3. Conflicts with other programs: Sometimes, the JNI error can occur due to conflicts with other programs running on your computer. This can happen if the other programs are using the same resources as Minecraft, such as memory or CPU usage.

How to Fix the JNI Error in Minecraft?

Now that you know what causes the JNI error in Minecraft, let’s look at how you can fix it. Here are some methods you can try:

Fix 1: Update Java

  • Step 2: Select “Java” from the search results.
  • Step 3: Click on the “Update” tab and then click on the “Update Now” button.
  • Step 4: Follow the instructions to install the latest version of Java.

Fix 2: Reinstall Minecraft

If the Minecraft installation files are missing or corrupted, it can cause a JNI error. To reinstall Minecraft, follow these steps:

  • Step 1: Open the Start menu and type “Control Panel” in the search bar.
  • Step 2: Select “Control Panel” from the search results.
  • Step 3: Click on “Programs” and then click on “Programs and Features.”
