Andreea, this looks like to be a regression as introduced by the updates you did yesterday on the Ubuntu nodes. Can you please investigate? With the release coming up today we have to ensure to not trap into holes. Thanks.

Mihaela, did a retrigger of those jobs succeed?

Comment 3

[Mihaela Velimiroviciu (:mihaelav)]

No, it fails the same way. I put those 2 machines offline for investigation

Removed java 7 but that didn't help at first on the 12.04 machine. So I also deleted jenkins folder and after reconnecting the java client, the retrigger passed. Did the same for 13.10.
