librxtxSerial.so 长双限制

Question

我正在尝试在 Ubuntu 14.04 (x64) 上使用 rxtx 库 (https://github.com/rxtx/rxtx) 从串口读取数据。我在 java 1.6 上使用运行构建了简单的 java 小程序（尝试使用 1.8 得到相同的结果）。

端口初始化 class - http://pastebin.com/KZFfGKtE
听众 class - http://pastebin.com/D4Wq0ctT

并且当侦听器想要读取输入时它崩溃并出现以下错误。

看起来这是一种原生 RXTX 库 (librxtxSerial.so) 问题。非常感谢任何帮助。

答案是...使用 JSSC (https://github.com/scream3r/java-simple-serial-connector)。有效。
