Description of problem:
The table name computed for an @ElementCollection of @Embeddable uses the entity name instead of entity table name

Version-Release number of selected component (if applicable):
Hibernate core 4.2 and later

How reproducible:
Consistently

Steps to Reproduce:
1. Provide a table name for a entity which differs from the entity name:

@Entity
@Table(name = "prod")
public class Product {
    ...
}

2. Add collection of embeddable to the above entity
    @ElementCollection(fetch = FetchType.EAGER)
    private Set<Part> parts = new TreeSet<Part>();

Actual results:
Hibernate 4 computes the join table name as Product_parts

Expected results:
The table name should be prod_parts

Additional info:
- Hibernate 3 (which used @CollectionOfElements rather than @ElementCollection) computed the join table name as prod_parts
- This may be the same as https://hibernate.atlassian.net/browse/HHH-5417
