javascript callbacks from JalviewLite do not work on Safari

JalviewLite callbacks are not available on OSX safari, since the JalviewLite.init() method cannot get a reference to the page's JSObect via 'JSObject.getWindow(this)'.

On Windows, a reference to the object can be obtained, but Java/Javascript function execution is erratic (from either direction), and all calls raise a MalformedURLException of the form :

java.net.MalformedURLException: no protocol:
