Java - Temporizador de java

Hola tengo un temporizador en java que se encarga de actualizar un jtable cada 5 segundos el problema que que cuando llamo a la funcion

(DefaultTableModel) listado.seColumCount(1); esta me falla y no se porque pasa eso pero esta comprobado que es esa funcion.

Aqui os dejo el error...
