Error Resolving: JNI Error "A JNI error has occurred" in Eclipse x86 Windows 8.1

The error "A JNI error has occurred" in Eclipse is usually associated with a mismatch between the Java Runtime Environment (JRE) and Java Development Kit (JDK) versions used for compilation and execution.

Problem Analysis

In the given code, the program is compiled and run using JRE version Java 8, while the compiler (Java 12) is a separate application that is part of the JDK.

Solution

To fix this issue, you can take the following steps:

Step 1: Uninstall Java 8 JRE

Remove the Java 8 JRE from your computer to eliminate the version conflict.

Step 2: Verify Java Version Consistency

Use the commands:

java -version
javac -version

to check that the same version number is returned for both the JRE and JDK.

Step 3: Recompile and Run

Recompile the program to ensure it's built using the correct Java version. Then, run it to verify if the error persists.

Additional Tips

Ensure that the correct JRE/JDK paths are set in Eclipse preferences (Preferences -> Java -> Installed JREs).
Restart Eclipse after making any configuration changes.
Consider using a single, compatible version of Java (both JRE and JDK). This eliminates potential versioning issues.
Check for additional error messages in the console or log files for more context on the JNI error.
