@Shiv_Gupta,
I know that you installed a new version but I suggest you download logstash zip edition from elastic again and descompact in a new folder like C:\NEW\_ELK\
[Download link](https://artifacts.elastic.co/downloads/logstash/logstash-6.2.2.zip)
Then try start logstash again.

@darsan55,
Did you try download the version that I sent before in a link ?
If yes, Did you install (descompact) in a different folder, ex: C:\NEW\_ELK\logstash-6.2.2?
Then did you try start again?

@Shiv_Gupta and @darsan55,
I searched something about this problem. Could you try one anything more?
It is necessary downloading a new jar version of jruby in this [link](https://repo1.maven.org/maven2/org/jruby/jruby-complete/9.1.16.0/jruby-complete-9.1.16.0.jar)
After, replace the jar file "\logstash-6.2.2\logstash-core\lib\jars\jruby-complete-9.1.13.0.jar" by this file that you downloaded.
Current version: jruby-complete-9.1.13.0.jar
New version: jruby-complete-9.1.16.0.jar
Then, try start logstash again and tell us what's happen.

Its very late to ask.. but did we tried installing a new java and pointing logstash to it?

Are you trying on personal laptop?
If yes, we can try a screen share. I am always interested in head banging issues. 🙂
Remove line 1 which is echo off
Add these echo points in your logstash.bat at line 50, just before starting logstash
echo %JAVA%
echo %CLASSPATH%
echo %JAVA\_OPTS%
echo %LS\_JAVA\_OPTS%
And paste the contents of
> \Java\jdk1.8.\*\*\*\jre\lib\ext
folder.

@Suman_Reddy1
I am not clear where to add this "\Java\jdk1.8.\*\*\*\jre\lib\ext" folder content because all these are jars, i m not sure where to add can you suggest me something.?
I will be happy if you can solve it while sharing the screen.

If you add these
echo %JAVA%
echo %CLASSPATH%
echo %JAVA\_OPTS%
echo %LS\_JAVA\_OPTS%
It will print environment info. So that I can compare my details with yours!
Please add these values to logstash.bat. It will ouput at the very initial steps of logstash startup
