/**
 * An InstantiationCopyPolicy is used to set an
 * org.eclipse.persistence.descriptors.copying.InstantiationCopyPolicy on an
 * Entity.
 *
 * InstantiationCopyPolicy is the default CopyPolicy if weaving is not used,
 * or if property access is used.
 *
 * A special CloneCopyPolicy is used if weaving and field access is used.
 *
 * An InstantiationCopyPolicy should be specified on an Entity,
 * MappedSuperclass or Embeddable.
 * <p>
 * Example:
 * <pre><code>
 * {@literal @}Entity
 * {@literal @}InstantiationCopyPolicy
 * public class Employee {
 * </code></pre>
