OK, so, you have a lot of places you are passing around a
DBusInterface. This will cause it to be auto-proxied. Try using a Path
type instead. However, I couldn't get your test running. Your test does:
DBus.Properties props =
DBus.Properties.class); List<Path> activeConns =
but that object (at least on my version of network manager) doesn't support
$ sudo dbus-send --system --type=method_call --dest=org.freedesktop.NetworkManager --print-reply /org/freedesktop/NetworkManager org.freedesktop.DBus.Properties.Get string:foo string:bar
Error org.freedesktop.DBus.Error.UnknownMethod: Method "Get" with signature "ss" on interface "org.freedesktop.DBus.Properties" doesn't exist.
To answer your specific questions:

Yes, this is correct, the bindings don't treat it specially at all.

Are you having the problem I described above? Is that the right path?

Declaring the return / parameter type as DBusInterface will do the
path/proxy auto conversion. Using (I think) Path instead won't. At least
that's the idea. I can't test it out on your code though because of the
above properties problem.
dbus-java/org/freedesktop/dbus/test/test.java:89 and 603
would be the bits of my internal test suite which test this.
