OH 2.1 snapshot, image widget IP camera problem

Having an odd problem with the latest snapshot.

I’ve always had a refreshing image widget showing the image from a security camera:

Image url="http://admin:PASSWORD@" refresh=100

On the latest snapshot this has stopped working with BasicUI and ClassicUI (and the iOS app). I get a blank screen and the camera logs numerous failed authentications (and annoyingly then locks me out for a while). The password is certainly correct, as it works fine from a browser.

Any thoughts?
