Description _ rkubacki 2006-11-22 15:05:08 UTC 
as a part of issue #57542 fix we are calling
InetAddress.getLocalHost().getCanonicalHostName() during startup to get a list
of hostnames for which proxies are not used. This can be very slow (10-15
seconds in environment with VPN turned on) and currently is done during
ModuleInstall and thus everything is blocked until this call is completed.

I am not sure if we really need canonical name. Petr J.: is it really important?

It should also be possible to make this code asynchronous so that main startup
sequence will not be affected.

Comment 2 Petr Jiricka 2006-11-22 15:27:52 UTC 
I must say I don't remember the exact circumstances of issue #57542, so I can
not really comment. Perhaps one option is to try to remove the canonical name
method call, and retest issue 57542 with this change. Cc'ing Milan, who can
comment on the conditions related to that issue.
Comment 3 Jiri Rechtacek 2006-11-23 10:14:07 UTC 
After discussion with Milan we agree that code seems as useless for current IDE.
Fix removed it.
