问题：
exception_access_inversion:不会写入核心转储
公西俊能
我试图用Java编写一个串行通信类，它将使用Java Simple serial Connector库连接到Arduino UNO。然而，每当我试图打开端口时，我都会在本机代码中遇到这个错误：
#
#Java运行时环境检测到一个致命错误:
#
#exception_access_visire(0xC0000005)at pc=0x0000006EC4B5BB,PID=6324,TID=6508

我所尝试的：到目前为止，我已经转到高级设置切换到微型转储。我已经重新安装了我所有的驱动程序，更新了Windows10，并重新下载了Java SDK。我目前正在使用Eclipse IDE，并且还删除了。metadata文件夹，因为有人建议它可以有所帮助。我真的不知所措，不完全确定如何解释日志文件或通常的错误。只有当我试图调用JSSC的openPort方法时才会出现此错误。当我试图使用RXTX来实现相同的目的时，它也会出现。不知道这里发生了什么，任何帮助都将不胜感激！
