hibernate3-maven-plugin hbm2ddl goal ignores sequence definitions and generates default hibernate_sequence instead
===

I have JPA annotated entity with ID defined as auto-generated property using sequences. But when I am trying to generate DDL with hibernate3-maven-plugin then my defined sequences are not generated, instead hibernate_sequence is there.

    @Entity
    @Table(name = "DUMMY")
    @SequenceGenerator(name = "DUMMY_SEQ")
    public class Dummy {
        private Long pk;
    
        @Id
        @Column(name = "PK", nullable = false )
        @GeneratedValue(strategy = GenerationType.SEQUENCE, generator="DUMMY_SEQ")
        public Long getPk() {
            return pk;
        }
    
        public void setPk(Long pk) {
            this.pk = pk;
        }
    }
I am expecting something like:

    create sequence DUMMY_SEQ;

in generated DDL. What I am doing wrong?
hibernate3-maven-plugin version is 2.2
hibernate-entitymanager version 3.4.0.GA
