> {{WritableDeserializer}} does not hold a reference to the Configuration 
> object, so it does not pass it to deserialized writables, but uses 
> ReflectionUtils.newInstance(writableClass, null), which results in objects 
> defining Configurable interface to be initialized with null configuration. 
> Serialization framework have been introduced in 0.17, so this bug affects 
> 0.17.
