Intermittent errors in the Sun trunk nightlies upgrade tests especially on Vista

This is a follow up issue of what was being discussed here: http://www.nabble.com/Lots-of-errors-in-the-sun-trunk--nightlies-especially-on-vista-to24489773.html

At this point, the errors seem to be intermittent and they seem to happen on both Vista and XP (as reported by Mamta), with special incidence on Vista.

Kathey said she's seen them as far as April 6th which is after the 10.5 branched.

Here is a list of failing tests when this occurs.
