/**
 * A custom deserializer that deserializes {@link URL} objects from its string representation. URLs can be deserialized
 * only if they have been serialized with {@link UrlSerializer}.
 * 
 * To become effective, this class must be registered as custom deserializer in file
 * META-INF/hessian/deserializers.
 * 
 * This new pair of serializer/deserializer was needed to quickly work around a bug in Hessian. Due to a change in the
 * URL class in Java 1.8.0_72, the standard object deserializer in Hessian is not able any longer to deserialize URLs
 * without errors. See #2590 for more information.
