import com.fasterxml.jackson.databind.JavaType;

 * Default {@link PolymorphicTypeValidator} used unless explicit one is constructed
 * (and, in 2.11, {@link com.fasterxml.jackson.databind.MapperFeature#BLOCK_UNSAFE_POLYMORPHIC_BASE_TYPES}
 * not enabled).
 * Does not do any validation, allows all subtypes. Only used for backwards-compatibility
 * reasons: users should usually NOT use such a permissive implementation but use
 * allow-list/criteria - based implementation.
 * @since 2.10
