Issue with upgrade from 4.0.1.1 to 4.2.1

It is unsupported to put anything inside jetty-base except editing start.d\idp.ini.  I suspect that something that used to work
serendipitously got broken with the move to jetty 10.

There is limited support for static data to be served out, but that's about it.  Our recommendation for what you want to do is to
deploy and manage your own container.  

If it were I, I would use jetty & procrun (which we ship as "shibd_idp.exe" and "shibd_idpw.exe") and look at the configuration that
the installer sets up - that's the only complicated part and with it being Windows you don't have any of the "The port numbers are
less than 1024 so you have to jump through hoops" to worry about.
