[ireport] iReport not starting using JRE 8

I have installed IReport 5.6 with Java 7: not working

I tried to install Java 6 and added the path to "ireport.conf" file like the attached screenshot and it worked fine :Denter image description here

So the steps is :

 Install IReport 5.6
 Install JDK 6
 Edit "ireport.conf" file like the below image and Enjoy ;)
