[midPoint] MidPoint switching to Java 8

[Radovan Semancik]

Hello,

MidPoint project will completely switch to Java 8 very soon. Most likely 
next week. Development master will be switched to Java 8, while support 
branches will remain on Java 7.

This means that MidPoint 3.5 release will work only in Java 8 
environment. With the planned 3.5 release (December 2016) we will 
completely drop Java 7 support.

Java 8 is a recommended environment for a long time. Java 7 is more than 
5 years old and there are serious issues with Java 7 (e.g. security 
patches). Java 7 support was officially deprecated in the last midPoint 
release (3.4.1). Therefore it is the right time to make the switch to 
Java 8 permanent.
