Description Jesse Glick 2007-05-11 09:47:35 UTC 
070504. Not sure what I did, but I think I clicked on Refresh while the progress
bar was running to get contents of AU centers. Note that I am having network
problems. That is no excuse for the display to freeze of course. It has been
dead for several minutes so I will have to kill the IDE.

It did actually recover several minutes later and tell me that it could not
connect to the UC.
Comment 3 Jiri Rechtacek 2007-05-11 10:04:48 UTC 
The part of problem is already fixed in M10. Networks operations are not called
from EQ.
Anyway the root of problem is java.net.URL.openStream() takes sometimes a huge
time if network is presently gone. If OS works offline then
java.net.URL.openStream() throws IOE immediately but if OS boots online and then
have loosed network connection java.net.URL.openStream() waits a couple of
minutes  till throws IOE. The caller cannot know whether network is working
(e.g. and downloading data) or network is broken.

Happened again in 070522, will attach new thread dump. My network connection is
fine AFAIK.

Still reproducible in M10 => increase the priority.

Plugin Manager UI is now blocked while initialization is running.
