org.hibernate.type.SortedSetType does not overwrite instantiate(int anticipatedSize)
------------------------------------------------------------------------------------

         Key: HHH-2014
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2014
     Project: Hibernate3
        Type: Bug

  Components: core  
    Versions: 3.2.0.cr3    
 Environment: Hibernate 3.2.0.cr3, affects all environments
    Reporter: Stefan Schulze
    Priority: Critical


org.hibernate.type.SortedSetType inherits the implementation of instantiate(int anticipatedSize) from org.hibernate.type.SetType. In the effect, a java.util.HashSet gets instatiated instead of a java.util.TreeSet.  Collections mapped with sort="natural" or sort="<T implements java.util.Comparator>" will never be sorted once they are retrieved from the database. Since is is neither possible nor makes it sense to create a TreeSet with an initial size, the missing implementation of instantiate(int anticipatedSize) may safely ignore the argument and delegate to instantiate().
