Работа с потоками «AWT-EventQueue-0» java.lang.IllegalStateException

ПРИМЕЧАНИЕ: Я поставил полный пример кода, чтобы сделать его исполняемым любым пользователем; мой настоящий код очень длинный!Работа с потоками «AWT-EventQueue-0» java.lang.IllegalStateException

я получить эти исключения ИНОГДА:

Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException:

Я работаю с потоками, которые выполняют задачу .. как этого

мне нужно поместить в одну панели другой новой панели, когда мероприятие происходит
