Ошибка RXTX 2.2pre2 с использованием внутри AWT/Swing

Question

Я использую библиотеку rxtx для подключения к последовательному порту. Для этого я настроил gui, используя разные вкладки. На первой вкладке показаны доступные устройства, вызывающие gnu.io.CommPortIdentifier.getPortIdentifiers() в библиотеке rxtx версии 2.2pre2 (os - последняя стабильная Ubuntu linux 32 бит).

Выполнение этого при запуске отлично работает. Но если я переключусь на другую вкладку и обратно, список должен быть обновлен (вызывается из флага stateChanged интерфейса StateChange для вкладки). Если я делаю это, сбой jvm. Я также попытался использовать rxtx 2.1.7, но все тот же вопрос.

Любая идея, почему это происходит?

RXTX используется в jFTDIserial (https://github.com/hanneseilers/jFTDIserial) самонастраивающаяся Java-библиотека для подключения к последовательным портам через несколько других библиотек. JFTDIserial отлично работает в автономном тесте.

Answer 1

Ошибка была связана с перезаписью родной библиотеки для rxtx из второго экземпляра библиотеки jFTDiserial.
