I would guess that script injector injects by default inside gwt frame.
You need to specify TOP_WINDOW because jsinterop are mapped to $wnd by
default.
Something like that (can't test right now)
ScriptInjector.fromString(js).setWindow(ScriptInjector.TOP_WINDOW).inject();
If you do this then you need to change your jsni test to
var p = new $wnd.ns.Person();
Hope that helps.
