Fallo en base de datos

[AdRii]

Hola tengo una base de datos en la que tengo que guardar desde una aplicacion java un numero de jugadores un array de string con el nombre de los jugadores, cuando mete el nombre de jugadores solamente la aplicacion guarda y carga de la base de datos perfectamente, sin embargo cuando va a guardar la lista de string sale un error como este...
