Radim Hopp commented on JBIDE-14725:
------------------------------------

I have tried it once again on JBT 4.1.0.CR1a and I managed to replicate almost whole scenario.

1. Disconnect from internet
2. Open preferences -> JBoss Tools -> JBoss Tools Runtime Detection
3. Click "Download"
ASSERT some message about internet unavailability should be shown
FAIL Nothing happens, just exception in Error Log
4. Connect to internet
5. Try invoke download-runtimes wizard once again.
ASSERT download-runtimes wizard should be opened
FAIL Nothing happens, just exception in Error Log

After restart, everything worked fine.
I made a little screencast: http://youtu.be/8gTJ_eiPZ7s
I'm reopening this issue and postponig it to some future version.

> 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...)
