Exception dans le thread "AWT-EventQueue-0" java.lang.ClassCastException: javax.swing.JTable

j'ai un code qui quand run génère une table en forme de swing qui contient un ensemble de cases à cocher qui peut être sélectionné ou non

lorsque je clique sur L'onglet Cochez toutes les cases, Je suis en mesure de sélectionner/désélectionner toutes les autres cases à cocher ci-dessous, mais lorsque je sélectionne une des cases à cocher ci-dessous individuellement, je reçois cette erreur:
