[news.eclipse.platform.swt] Re: JFace examples in Second Edition of Clay

Hi Chris,

ISafeRunnable is in the org.eclipse.core.runtime plugin, so you'll need its
jar on your buildpath as well.  I think this is the last one you'll need to
add, but if this doesn't get you running then you should post a followup to
the eclipse.platform.rcp newsgroup since that is where jface and its
dependencies (excluding swt) live.
