The behavior of TableColumn.sizeWidthToFit() method was changed in JDK1.3.0M.
The method does not change minimum and maximum width of the TableColumn now.
See example.
It is incompatible change, the old behavior should be restored.

the javadoc 1.2.2, 1.3.0K says: "
public void sizeWidthToFit()

      Resizes the TableColumn to fit the width of its header cell. If the maximum
      width is less than the width of the header, the maximum is increased to the
      header's width. Similarly, if the minimum width is greater than the width of
      the header, the minimum is reduced to the header's width.
      See Also:
            setPreferredWidth(int)
"

the javadoc 1.3.0M says: "
sizeWidthToFit

public void sizeWidthToFit()

      Resizes the TableColumn to fit the width of its header cell.
      This method does nothing if the header renderer is null
      (the default case).
      See Also:
            setPreferredWidth(int)
"

The method works incorrectly. width=15 Should be 10
