Grails not running

Question

I am trying to run grails in my laptop, I have installed jdk 1.8.0 and jre8, I have set JAVA_HOME and GRAILS_HOME correctly. When I type %JAVA_HOME% or %GRAILS_HOME% in command prompt, it displays correct paths. But when I try to run any grails command, I get the following error:

My laptop has windows 8. Any help regarding this would be greatly appreciated.

I was using java8, I tried using java7 and it worked fine! Apparently grails does not work with java8
