Error: a jni error has occurred, check your installation and try again exception in thread "main" java. lang.: slp/core/cli has been compiled by a more recent version of the java runtime (class file version 53.0), this version of the java runtime only recognizes class file versions up to 52.0

You need to make sure that the is a sub class of the linkage bug. Its a class format error. And this error is given by JVM as it tries to study the class file who minor and major version numbers are outdated. This error has been arising since Java 1.2 and is being thrown during the run time as well as most precisely during the linking phase.

It indicates that the current JVM is not supporting the class file of the application,

Hence,we must verify the installed version of java.

Explanation:

You need to make sure that the is a sub class of the linkage bug. Its a class format error. And this error is given by JVM as it tries to study the class file who minor and major version numbers are outdated. This error has been arising since Java 1.2 and is being thrown during the runtime as well as most precisely during the linking phase.

It indicates that the current JVM is not supporting the class file of the application,

Hence,we must verify the installed version of java.

And we need to install the Java latest version.

We can find the Java version by  

Java -version

The following class can help in finding the version number of the class file.

FindMajorVersion.java:

import java.io.FileInputStream;

import java.io.InputStream;

import java.io.File;

import java.io.IOException;

import java.io.DataInputStream;

public class FindMajorVersion {

    public static void main(String[] args) throws IOException {

         // Verify at least one argument is being passed to the application class.

         if(args.length < 1)

              throw new RuntimeException("Usage: FindMajorVersion <path_to_class_file>");

         // Make a buffer for storing the first 8 bytes of a file.

         byte[] buffer1 = new byte[8];

         // Create an InputStream  

         InputStream is1 = new DataInputStream(new FileInputStream(new File(args[0])));

         // Read the first 8 bytes of the file.

         is.read(buffer);

         // Print out the major version number.

         System.out.println(buffer1[7] + " (" + String.format("0x%x", buffer1[7]) + ")");

         // Shut down the stream.

         is.close();

    }

}

You can thus find the appropriate version, and upgrade the java which is installed to the latest version. And thus, you can make it certain that all the Java apps are successfully executed inside the system.
