Publiqué una respuesta paraJava TableModelListener y Live Feed Listener?, pero recibo un comentario de - kleopatra

nonono - you never change the notifier in receiving a change event. 
As to probable effects, think: nasty loops. As to code sanity, think: 
indecent intimacy. It's the task of the model itself to internally 
update related values if necessary.

alguien puede explicarme qué es lo que cambia el notificador al recibir un evento de cambio, qué podría suceder, lo que realmente quiere decir, porque como intenté todo lo que sé, solo recibo Excepciones de RepaintManager del bucle muy rápido,

Nunca obtengo otra Excepción, donde

I multiplaeyd que a la matriz de 50 x 1000,

with prepareRenderer (cambie el color por valor positivo / negativo)

con frecuencia de actualización 175 milisegundos

code demostró cambiar el notificador y otras dos (tal vez correctas) cómo hacer eso
