I am trying to run ES on my server, and I got this error:
```

Could not find the main class: org.elasticsearch.tools.java_version_checker.JavaVersionChecker. Program will exit.
```
It seems that the issue is related to the java version, Could you please advise if I do something wrong or there a special configuration should be taken before running the ES?
Please note that we have the following JDK versions install in the server:
- jdk1.7.0\_25\_32bit
- jdk1.7.0\_25\_64bit
- jdk1.7.0\_72\_32bit
- jdk1.7.0\_72\_64bit
- jdk1.8.0\_74\_64bit

you need a newer version of java (at least java 8) in order to run Elasticsearch

I have already java 8 in the server, the problem was the JVM is pointed to java 6, However, I have changed the $JAVA\_HOME variable to the java 8 path, and it is working for me.
