java.util.Properties.stringPropertyNames()
Returns a set of keys in this property list where the key and its corresponding value are strings, including distinct keys in the default property list if a key of the same name has not already been found from the main properties list. Properties whose key or value is not of type String are omitted.
The returned set is not backed by the Properties object.
