> The method addProperty not append a NEW property in the file when the property not exist.
>  I work with java 7.
>  I see that the new property don't compare in keys list, and when the property is new.
> Example:
> {code:java}
> PropertiesConfiguration config = new PropertiesConfiguration();
> PropertiesConfigurationLayout layout = new PropertiesConfigurationLayout(); 
> layout.load(config, new InputStreamReader(new FileInputStream(zookeeper))); 
> String port = instance.getPort();
> config.setProperty("clientPort", port); 
> config.addProperty("prova","prova"); 
> layout.save(config, new FileWriter(zookeeper));
> {code}
> The property 'prova' don't appear in the file property after the save.
> I see in PropertiesConfigurationLayout.save, line 565, that the method  'getKeys' don't contain the property 'prova', and the save lost this property.
