So these warning messages occurred only 6.1.148-rc1. All the other 6.x RCs were fine. Despite these warnings,
6.1.148-rc1 built fine, and seemed to work ok. However I think these warning should not be present. They didn't occur in
any of the 6.1.x RCs before, and I think I tested the last 20 or 30 of them.
Am I the only one who has seen this? Has anyone looked into this?
