Hi ,
My discoverer plus version 11.1.1.3 is working perfectly in java7 update71 -windows-x64 , even the certification matrix supporting only till java1.6 . When I updated my JRE to java8 update 25 -windows-x64, after bypassing the security exception by adding the url in the exception list, I got the below error as in the image attached.

I have JDK 7 in my server side and updated to java8 update 25 in my client side.
I am not sure about the certification matrix , whether it is saying only JDK or both JDK and JRE.
Kindly share your ideas.
Thanks,
John.
