Исключение в библиотеке JDK Swing

Question

Получение ниже NullpointerException в библиотеке Java. Я подозревал, что проблема связана с асинхронным обновлением значений поля со списком в фоновом потоке после входа пользователя в приложение.

Примечание: эта проблема поступает в производство. Любой обходной путь или исправление будет принята с благодарностью.
