Questions about OSUser

I am having a number of problems with OSUser and I am trying to find the
right list to post my question to.  So, if this is the wrong list then I
am sorry.

Here is a simple test that I am using:
===================================================================
import com.opensymphony.module.user.UserManager;
import com.opensymphony.module.user.DuplicateEntityException;
import com.opensymphony.module.user.ImmutableException;

public class Test
{
    public static void main( String[] args )
    {
        UserManager um = UserManager.getInstance();
        try
        {
            um.createUser( "cwidhelm" );
        }
        catch( DuplicateEntityException e )
        {
            e.printStackTrace();  //To change body of catch statement use
Options | File Templates.
        }
        catch( ImmutableException e )
        {
            e.printStackTrace();  //To change body of catch statement use
Options | File Templates.
        }

        System.out.println( um.getGroups() );
    }
}

===================================================================

Here is the exception that I am getting:
===================================================================
com.opensymphony.module.user.DuplicateEntityException: user cwidhelm
already exists
 at
com.opensymphony.module.user.UserManager.createEntity(UserManager.java:325)
 at com.opensymphony.module.user.UserManager.createUser(UserManager.java:184)
 at com.contego.Test.main(Test.java:14)
[admin, user]

===================================================================

I am using Hibernate as my persistance layer.

I know that this is a wide open question.  Let me know if there is
anything else that I can send that might help answer this.

Thanks,

Chris
