Is everything clean on that machine? If anything happens on the screen (outside of Eclipse), it will take the focus and let the tests fails. Usual suspects are screen locks and update/install dialogs.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
Please reopen with more details if it is still reproducible.
