> Isn't LAST_COLUMN is meant to be different than specifying a particular column ? Suppose the app specified the resizing column and expects it to be unchanged after changing mode back to a previous mode ? If the app changes the mode would it really expect now a particular column to be specified ? Is a specific test going to be hard ? No one actually routinely manually tests this in SwingSet, and we don't do integration testing any more.

As per the `JTableHeader.setResizingColumn` spec,
`Application code will not use this method explicitly, it is used internally by the column sizing mechanism`
so app will/should not specify the resizing column directly so I guess it's alright to expect this will not get changed..
I also tested with different autoresize modes and it works fine.

Regarding test, I am not able to think of any automated way to test this, so if it can be manual, then I thought it will be as good to test it out through SwingSet2 since manual tests also is run only during ATR...
