There is a subtle behavioral difference between the old CONSTRAINED_RESIZE_POLICY and CONSTRAINED_RESIZE_POLICY_SUBSEQUENT_COLUMNS that people might notice and may not like.  The difference is that the old policy works similar to CONSTRAINED_RESIZE_POLICY_LAST_COLUMN until the last column cannot be resized, then it resizes one before it.

Try tests/manual/controls/ATableViewResizeTester.java to see the behavior.
