I believe Logback behaves similarly to Spring, but it's Jetty's
keystore path property that I think will need to be of the form
<SystemProperty name="idp.home">/<Property name="jetty.keystore.path"
/>, because Jetty does not support nested properties AFAICT. Really
that's why I was asking, whether or not to use <SystemProperty /> or
<Property /> in the Jetty XML for idp.home.
