Thanks Toby, And no surprise, moving my URL Fetch from the GWT client to the GWT serverimpl makes it all work fine. And from the GWT list: java.net package is not supported by GWT

It would be nice if the Plugin could distinguish GWT client classes from all others (including GWT serverimpl classes) and validate accordingly, but that might be some unpleasant work.
