/**
 * JPA 2.1 converters to turn ThreeTen back port types into legacy {@link Date}s. To activate these converters make sure
 * your persistence provider detects them by including this class in the list of mapped classes. In Spring environments,
 * you can simply register the package of this class (i.e. {@code org.springframework.data.jpa.convert.threetenbp}) as
 * package to be scanned on e.g. the {@link LocalContainerEntityManagerFactoryBean}.
 *
 * @author Oliver Gierke
 * @see https://www.threeten.org/threetenbp
 * @since 1.8
 * @deprecated since 2.4, use JSR-310 types as replacement for ThreeTenBackport.
