A DESCRIPTION OF THE PROBLEM :
NullpointerException when trying this:

        JTableHeader header = new JTableHeader();
        TableCellRenderer headerRenderer = header.getDefaultRenderer();
        JTable table = new JTable();
// table.setAutoCreateRowSorter(true);
        headerRenderer.getTableCellRendererComponent(table, "test", false, true, -1, 0);


uncommenting the setAutoCreateRowSorter line does not help.
Trying to set an own RowSorter does not help either.

This worked fine in 1.6.0_03.
