DefaultTableModel.setColumnIdentifiers(columnNames) fails when count+1 new cols

Bug in setColumnIdentifiers(columnNames) where columnNames.size() is greater than original columnCount. What happens is we assign newColumnNames to oldColumnNames without setting the ColumnCount size. Without setting the new columncount before displaying causes us to make a reference to a nothing value
assigned to the new column. This in turn causes a ArrayIndoexOutOfBoundsException to be thrown when getValueAt(0,newColumn).
Talked with milne@eng about this. He said that he would fix this one.
