> Since Ambari 2.1.0 we support Java 1.7.0 as minimal requirement and begin to
> use 1.7+ language constructions. Previously minimal language level was 1.6
> and due to different reasons user can miss notification about this change and
> can try to upgrade Ambari 2.0+ to Ambari 2.1 on Java 1.6, which will cause a
> lot of unexpected errors in different places.
