Почему мое окно в Java (JFrame) вылетает, когда я дважды щелкаю JTextField? ⇐ JAVA

[Anonymous]

Я написал эту небольшую программу для конкретной утилиты, еще не оптимизировал ее, но пока все работает как задумано, но когда я случайно дважды щелкаю по JTextField, происходит сбой, и я понятия не имею, почему. (JTextField находится в строке 62)

Вы не должны с ним взаимодействовать, и я установил для параметра Editable значение false, но иногда он просто вылетает из ниоткуда, а иногда действительно отправляет ошибку
