Yah, but I'm anyway looking forward to using Java8. I think we will start developing with it in my company earliest in 2020 ... No kiding. I guess other places might be similar. You have to convince the architects that lambdas are beneficial while those guys only care about the CTO and would never talk to some developer. Seriously, architects being decoupled from development was the worst mistake in the last 10-15 years in Java development ...

Sorry for the rant. Couldn't control myself for a little moment ... ;-).
