Exception when hiding a column in JTable using Java version 1.3

[Nige]

We trigger the hide/show of columns in a JTable from a JPopupMenu
displayed on a right mouse button click. When the hide column menu
option is selected we call the
TableColumnModel.removeColumn(TableColumn) function and an exception
is thrown.

The same code works with no problems in Java version 1.2

The exception is as follows:

Exception occurred during event dispatching:

This happens if you modify the TableColumnModel while dragging is in
process (which is between button press and release) such that the dragged
column is removed.

Either use SwingUtilities.invokeLater to remove the column, or manually
set the JTableHeader's draggedColumn/Distance to null/0 and repaint it.
