The Assert class in jface is now deprecated
in favor of the org.eclipse.core.runtime.Assert class (which is defined
in the org.eclipse.equinox.common plug-in).
I've fixed all the references in the
JFace plug-in, but did not touch JFace data binding or any other non-JFace
So if you see warnings showing up in
your code, this is why.
For reference see
