Problemas no jTable

Programação Java
#1

Qual é o motivo do erro abaixo na chamada ?changeSelection? de um jTable?

Exception in thread “Alternador de Planta” java.lang.ClassCastException: sun.java2d.NullSurfaceData cannot be cast to sun.java2d.d3d.D3DSurfaceData

Caro Marcos,

Como você havia comentando estou lhe enviando o código fonte completo onde ocorre o problema. E importante ressaltar que este código fonte está acelerado para que o erro ocorra com maior facilidade, mas mesmo assim aqui em minha maquina ele foi ocorre depois de uns 45 minutos de execução. Alem do erro principal, você vai notar que em alguns momentos da execução do programa partes da jTable será impressa em regiões da janela que não deveria ser impressa.
