[news.eclipse.newcomer] "no socket available" junit error

[jamesmct@xxxxxxxxxxx (James )]

I'm trying a very basic junit test on a very simple class.  Running the 
test gives the error message, "no socket available".  None of my classes 
or tests involve any internet connections.  I created and ran the JUnit 
tests through the right-click menu.  I downloaded my version of Eclipse 
less than a week ago.

I've seen these forum messages that seem to be the same problem, but none 
are answered...

(I also found a French and a German thread.  I checked these in Babelfish, 
and they have no answers either)

This is probably a very simple problem, does anyone have any ideas?

Thanks.
