Description

The current code iterate through LoadablePropertiesSource as follows:

          for (PropertiesSource ps : sources) {
                if (ps instanceof LoadablePropertiesSource) {
                    LoadablePropertiesSource lps = (LoadablePropertiesSource) ps;
                    Properties p = lps.loadProperties();
                    prop.putAll(p);
                }
            }

As sources is ordered by Order, lower priority sources may override higher ones.
