----------------------------------------

Thanks, I can see that early-access is checked in a separate thread (this was the purpose of JBIDE-18217).
On main thread, we can see

[~fbricon] Shouldn't we put some asynchronism as well in ProxyWizardManager ?

> Imagine a situation where you are behind firewall which blocks HTTP/80.
> You unpack fresh eclipse and install jbosstools. After installation you are prompted to restart eclipse. But eclipse is blocked at startup for several minutes - there is blocking central thread which cannot access web because of firewall.
> If you don't forget to setup proxy in eclipse you won't experience this. But otherwise you will be stucked on eclipse startup. And that is bad user experience.
> I would suggest to fix it so, that eclipse can at least start - just central content is not loaded when http is blocked.
