Question

我目前正在尝试打开一个串行端口以向芯片发送一些数据，但我收到错误消息，java运行时环境已检测到致命错误。这是控制台日志。

# A fatal error has been detected by the Java Runtime Environment:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000000007110b5db, pid=21920, tid=23116

导致错误的函数应该打开后端/板通信端口。这是函数

public boolean openPort() throws SerialPortException {
        if(portOpened){
            throw new SerialPortException(portName, "openPort()", SerialPortException.TYPE_PORT_ALREADY_OPENED);
        }
        if(portName != null){
            boolean useTIOCEXCL = (System.getProperty(SerialNativeInterface.PROPERTY_JSSC_NO_TIOCEXCL) == null &&
                                   System.getProperty(SerialNativeInterface.PROPERTY_JSSC_NO_TIOCEXCL.toLowerCase()) == null);
            portHandle = serialInterface.openPort(portName, useTIOCEXCL);//since 2.3.0 -> (if JSSC_NO_TIOCEXCL defined, exclusive lock for serial port will be disabled)
        }
        else {
            throw new SerialPortException(portName, "openPort()", SerialPortException.TYPE_NULL_NOT_PERMITTED);//since 2.1.0 -> NULL port name fix
        }
        if(portHandle == SerialNativeInterface.ERR_PORT_BUSY){
            throw new SerialPortException(portName, "openPort()", SerialPortException.TYPE_PORT_BUSY);
        }
        else if(portHandle == SerialNativeInterface.ERR_PORT_NOT_FOUND){
            throw new SerialPortException(portName, "openPort()", SerialPortException.TYPE_PORT_NOT_FOUND);
        }
        else if(portHandle == SerialNativeInterface.ERR_PERMISSION_DENIED){
            throw new SerialPortException(portName, "openPort()", SerialPortException.TYPE_PERMISSION_DENIED);
        }
        else if(portHandle == SerialNativeInterface.ERR_INCORRECT_SERIAL_PORT){
            throw new SerialPortException(portName, "openPort()", SerialPortException.TYPE_INCORRECT_SERIAL_PORT);
        }
        portOpened = true;
        return true;
    }

任何有关如何解决此问题的想法将不胜感激！
