When initializing Configuration with a XML file this will call the XML constructor and the "trustedProxies" variable isn't initialized, eventually this will throw an exception at Configuration:966 "for (Network trustedProxy : trustedProxies)". This is a version breaking bug for whoever uses configuration files.

Fix is simple, change Configuration:185 to initialize the variable: "private List trustedProxies = Collections.emptyList();".

This variable initialization can then be removed from Configuration default constructor.
