/**
* A type that maps between a {@link java.sql.Types#VARBINARY VARBINARY} and {@link Serializable} classes.
*
* Notice specifically the 2 forms:
* - {@link #INSTANCE} indicates a mapping using the {@link Serializable} interface itself.
* - {@link #SerializableType(Class)} indicates a mapping using the specific class
*
* The important distinction has to do with locating the appropriate {@link ClassLoader} to use during deserialization.
* In the fist form we are always using the {@link ClassLoader} of the JVM (Hibernate will always fallback to trying
* its classloader as well). The second form is better at targeting the needed {@link ClassLoader} actually needed.
