Subject Re: [DISCUSSION] using JDK8 in OM
Date Tue, 30 Aug 2016 01:26:34 GMT
it's easy to test :)
open downloaded jnlp file change
<j2se version='1.7+'/>
to be
<j2se version='1.8+'/>

and run it using Java7

you will get:
1) warning from javaws: "Your java is too old, please update"
2) another warning: "This application would like to use version of Java
1.8+"
