And the more interesting part: Wizard is not working after reconnecting to the internet. It's not even working after restarting eclipse. It starts to work again with another workspace. 

In a nutshell, when you try to invoke runtimes-download wizard when offline, it will not work in that workspace no matter what (reconnecting to internet, restarting eclipse...)
