TableColumn DWT.LEFT causes seg fault

[Barry Denton]

for (int i=0; i<5; i++) {
                TableColumn column = new TableColumn (table, DWT.NONE);/
                            /NONE,LEFT,RIGHT.CENTER,LEAD.TRAIL
                column.setText (titles [i]); }

If you use anything but NONE it causes a seg fault
Docs say LEFT RIGHT CENTER
Addressbook uses NONE which works
DWT.d says LEAD and TRAIL also
