Я пытаюсь прочитать из последовательного порта с использованием Java. Я получил его читать из последовательного порта, но когда я иду, чтобы закрыть его я получаю эту фатальную ошибку

Answer 1

Проблема достаточно ясно, как указано в консоли вывода:

Native lib Version = RXTX-2.2pre2 
Java lib Version = RXTX-2.1-7 
WARNING: RXTX Version mismatch 
    Jar version = RXTX-2.1-7 
    native lib Version = RXTX-2.2pre2 

RXTXComm.jar является несовпадающими и librxtxSerial.jnilib ожидает другую версию. Скорее всего, вы можете скопировать правильные версии RXTEXComm.jar и librxtxSerial.jnilib в /Library/Java/Extensions или скопировать родную версию в приложение; это может решить проблему.

Также пожалуйста, напишите вывод:
