      static java.lang.String replaceProperties​(java.lang.String value, java.util.Hashtable<java.lang.Object,​java.lang.Object> staticProp, IntrospectionUtils.PropertySource[] dynamicProp)
      Replace ${NAME} with the property value.
      static boolean setProperty​(java.lang.Object o, java.lang.String name, java.lang.String value)
      Find a method with the right name If found, call the method ( if param is int or boolean we'll convert value to the right type before) - that means you can have setDebug(1).
