hbm2hbmxml task generates error for @ElementCollection annotation
-----------------------------------------------------------------

                 Key: HBX-1177
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1177
             Project: Hibernate Tools
          Issue Type: Bug
          Components: ant
            Reporter: Grzegorz Aniol


Affected version is 3.4.0CR1.

I'm running hbm2hbmxml task from ant script to generate hibernate mapping files based on annotations in entities. 
I'm getting an error: "Expression property.cascade is undefined on line 10, column 14 in hbm/map.hbm.ftl" for an entity which is using @ElementCollection annotation.

====================================================================
Here is the example of a class:
====================================================================

@Entity
@Table(name = "configentry2")
public class ClassA {
    
    @Id
    @Column(name = "id")
    private int id;
	
    @ElementCollection
    @MapKeyColumn(name = "key")
    @Column(name = "value", columnDefinition="TEXT")
    @CollectionTable(name = "configentry_map2", joinColumns = @JoinColumn(name = "configentry_id"))
    @ForeignKey(name = "fk_belongs_to_config")
    private Map<String, String> entries;
    
}


====================================================================
Here is the full exception stack:
