Firefox 57 Quantum on non-Linux: request not available in intercepts

[Martin Haase]

Hi list,

we want to report a strange behaviour with the new Firefox on Windows or
Mac: When the IdP should show an intercept view that contains the usual

    $request.getContextPath()

it will fail, showing the "stale request" error page. From the logs it
looks like this $request variable is either not accessible or does not
have the getContextPath() method. We could not reproduce it on all of
our servers, this particular was a

    CentOS Linux release 7.4.1708 (Core)

    openjdk version "1.8.0_144"

    Shibboleth IdP Version 3.3.0

It would be nice if someone who has seen the same would share their
experience. The workaround in this case was very easy, since this
particular method call always returns "/idp", we just hard-coded it.

Regards,

Martin
