hilo generator can generate negative numbers because of arithmetic overflow
---------------------------------------------------------------------------

         Key: HHH-2397
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2397
     Project: Hibernate3
        Type: Bug

  Components: core  
    Reporter: Steve Ebersole
 Assigned to: Steve Ebersole 
     Fix For: 3.2.3


org.hibernate.id.TableHiLoGenerator#generate can potentially generate negative numbers because of the possibility of overflow due to the handling of the "clock over" multiplication using int multiplication.  The solution is to force one of the operands to type long.
