008/**
009 * A non-JPA standard alternative to using <code>@Column(nullable=false)</code>
010 * or javax validation <code>@NotNull</code>.
011 * <p>
012 * We would typically prefer to use the standard annotations but with entity beans
013 * written in Kotlin as constructor properties the javax validation <code>@NotNull</code>
014 * is applied as parameter on the constructor rather than as a property mapping.
015 * </p>
016 * <p>
017 * So it is generally not ideal to use this non-standard JPA annotation but some may prefer
018 * it style wise - especially with Kotlin.
