That's a given IMO. For my work projects, there is so much inertia anchoring to Java 7 for various reasons.
One of the many fun things of FOSS for me is that things move faster than for work projects. So keeping on hearing that we must stay on Java 7 is not great. Yeah, there is the multi jar things and Java 9 thing but that is not the same as just moving to Java 8 plain and simple. Gary
