Comment 1 Jakub Cernohorsky CLA 2016-02-24 10:31:05 EST 
I have encountered similar problem - when using local cntlm proxy on windows with Oomph, sometimes eclipse looses ability to show proxy settings in preferences (shows The currently displayed page contains invalid values) and the proxy itself does not work correctly.

The fix is to run eclipse with option -clean or manually delete directory configuration/org.eclipse.osgi. The setting - configuration/.settings.org.eclipse.core.net.prefs is still valid and after start with -clean it works as it should.
