  Take this entity:
  public class Simple {
  private int id;
  private String name;
  Take this orm.xml entry:
  MySchema
  public class Simple {
  private int id;
  private String name;
  Take this orm.xml entry:
  <persistence-unit-metadata>
  <persistence-unit-defaults>
  <schema>MySchema</schema>
  <delimited-identifiers/>
  <!-- The cascade-persist
  entry causes an issue: -->
  <cascade-persist/>
  </persistence-unit-defaults>
  </persistence-unit-metadata>
  <entity class="hat.entities.Simple"
