org.hibernate.test.hql.ScrollableCollectionFetchingTest#testScrollingJoinFetchesForward unsupported by DB2
----------------------------------------------------------------------------------------------------------

                 Key: HHH-3483
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3483
             Project: Hibernate Core
          Issue Type: Bug
    Affects Versions: 3.2.6
         Environment: DB2
            Reporter: Gail Badner
            Assignee: Gail Badner
             Fix For: 3.2.x, 3.3.x


Test org.hibernate.test.hql.ScrollableCollectionFetchingTest#testScrollingJoinFetchesForward uses scroll mode FORWARD_ONLY, but DB2 requires SCROLL_INSENSITIVE and SCROLL_SENSITIVE for scrolling.

This is not a bug. According to the JDBC spec, a TYPE_FORWARD_ONLY ResultSet is non-scrollable, so isAfterLast does not need to be supported.

The fix is for DB2Dialect to override Dialect.supportsResultSetPositionQueryMethodsOnForwardOnlyCursor() and return false.
