Duplicate index name in generated DDL for @Embeddable types in Hibernate

Issue

• An @Embeddable type is defined with a column index

  ...
  import org.hibernate.annotations.Index;
  ...
  @Embeddable
  public class Title implements Serializable {
      @Index(name = "title_idx")
      private String theTitle;
      ...
  }
  

• The @Embeddable type is used in several entities (included via @Embedded)

• When generating DDL, Hibernate attempts to create a database index with the same name (e.g. 'title_idx') for each entity
