Move to JDK8

[Erik Joelsson]

I managed to reproduce on Thursday and have a fix. This wasn't the only 
problem however, and I'm working on the rest. The office kinda got in 
the way. Should be able to push a fix sometime this week.

Over time we have realized that would be hard, both for consumers getting it all in their face at once, and for us, having to make sure we cover everything in one go. We recently decided to instead try to get small chunks in at a time, and instead of replacing the old system, add it as an alternate system until we make the switch. This way, we will get a lot more visibility and people will be able to try it out in their actual daily work.
