Css issues post GWT 2.5 Upgrade?

[kevin]

I recently upgrade to 2.5 and it seems like there is a new bug somewhere within the CssResource stuff. I think the bug only happens in development mode but after refreshing my application a couple times, certain css classes seems to get overwritten or merged with other css classes.  I can't seem to narrow it down any more than this but I was wondering if anyone else is seeing this issue.
