vagrant@vagrant-ubuntu-trusty-64:~$ java -jar selenium-server-standalone.jar

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/openqa/grid/selenium/GridLauncherV3 : Unsupported major.minor version 52.0

I managed to fix this by replacing the base box in the vagranfile:

config.vm.box = "ubuntu/trusty64"
config.vm.box_url = 'https://vagrantcloud.com/ubuntu/boxes/trusty64/versions/14.04/providers/virtualbox.box'

becomes:

config.vm.box = "bento/ubuntu-16.04"
