The method you used in 5.0.14 is no longer allowed. If you search through
the archives you will find out why; though as far as I recall, it is due to
the method being insecure or causing potential sharing of variables across
user sesssions.

So you have to replace it with something else.  Personally I moved this
initialisation to onActivate for directly accessed pages. For redirect pages
(your situation), you have to change the code to something like:

class Page1 {
@InjectPage
private Page2 redirectPage;


void onActive() {
    redirectPage.setFoobar("widgets");
    return redirectPage;
}

Other solutions may work too.
