I uninstalled Eclipse IDE due to this issue. Then I tried to run java program in my Linux mint Terminal. So I started with a small code

public class Myth{
public static void main(String[]args){
System.out.println("Hii There");

and run it by giving commands javac Myth.java and java Myth but insted of giving output it gives the following error

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=Myth, offset=6

means, that some of the libraries in your project are using diferrent version of java , and set accordingly in path. Quick things to resolve this:

$>which java

output->location of current java (eg. /usr/bin/java)

java --version

output->1.7.0 or 1.8.0 if this is the case , try switching version, for this do the following:

export JAVA_HOME=<path to diff java version sdk>
export PATH=$JAVA_HOME/bin:$PATH

This allows new path to come in front of old path, also for eclipse specific errors, take a look at eclipse cache in home directory(.eclipse folder in your project). You may safely delete this directory along ith .project files if any and recompile.

Edit: Offset=6 means your current version for java(JDK) is 1.6. Try switching it to later versions. Also check that you are using Jdk path and not jre path

  • after the command java --version terminal gives the following output JVMJ9VM007E Command-line option unrecognised: --version Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. – user Jul 20 '18 at 6:12
  • java -v, would also do it, there should be no spaces. If it is then your current java path is something like (/usr/java/jre1.x.y/) instead it should be (usr/java/jdk/1.x.y) – Pavan Kate Jul 20 '18 at 6:16
  • my java path is /usr/java/jre1.8.0_171 and after changing that the error is still active – user Jul 20 '18 at 6:25
  • change it to /usr/java/jdk1.8.0_171 . If you dont have a jdk installed get it from oracle site by accepting icense agreement, its free. oracle.com/technetwork/java/javase/downloads/… see java jdk 1.8 u171, and download jdk – Pavan Kate Jul 20 '18 at 6:30
