**NEM requires Java 8**.
Seriously? Soooo.. There is no real intention for this coin to be used by the general public for quite some time to come? I know programmers just love to play with shiny new things but someone should have smacked them upside the head and said a big fat no to that one.
You can install Java 8 just like 7. We provided a link too so what is your problem ?
You're the first one to complain so you might not want to talk about the "general public" here.
