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.
