> {{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.
