```
public class UniqueConstraintHolder
extends Object
```
UniqueConstraint annotations are handled via second pass. I do not understand the reasons why at this time, so here I use a holder object to hold the information needed to create the unique constraint. The ability to name it is new, and so the code used to simply keep this as a String array (the column names). Isn't this ultimately the same as org.hibernate.cfg.IndexOrUniqueKeySecondPass?
