Description Oleg Besedin CLA 2010-10-13 10:51:40 EDT 
Using I20101012-0800, when importing a project set, the error log gets filled with stack traces like this:

fix

I can reproduce this issue when I import preferences a second time. When I import preferences to Eclipse with a clean configuration, first import is passed without this exception. I have attached a fix.

Comment 3 Dani Megert CLA 2010-10-19 08:52:38 EDT 
I get this with these simple steps:

1. start new workspace
2. check out a project from CVS

Caused by bad fix for bug 242057.

Setting to 'major' since "Preference node "org.eclipse.core.net" has been removed" sounds scary.
Comment 4 Wojciech Galanciak CLA 2010-10-20 05:48:00 EDT 
Yes, you are right that it sounds scary :). Anyway, I have attached fix for this bug and now it is waiting for Szymon's review.
Comment 5 Olivier Thomann CLA 2010-10-20 09:11:32 EDT 
I also got it checking out from CVS WTP bundles.
Comment 6 Szymon Brandys CLA 2010-10-25 10:30:09 EDT 
Released in HEAD.
