Depency change between Vaadin 6.7.9 -> 6.7.10++ ?

General

Hello,

I’ve got a strange problem when I’m updating Vaadin 6.7.9 to 6.7.10 or 6.8++.

The answer can’t be null. It isn’t possible. Did vaadin changed any depency in the version 6.7.10 that use or implement a NamingEnumeration or something else that could be responsible for this?
