I'm getting the same exception, when I tried to instantiate SerialPortManagerContext class, I received RuntimeException,
The constructors are:
public SerialPort openSerialPort(String var1) throws NoSuchPortException, PortInUseException, UnsupportedCommOperationException {
throw new RuntimeException("stub");
}
public SerialPort openSerialPort(String var1, int var2, int var3, int var4, int var5, int var6, int var7) throws NoSuchPortException, PortInUseException, UnsupportedCommOperationException {
throw new RuntimeException("stub");
}
public SerialPort openSerialPort(String var1, SerialPortParameters var2) throws NoSuchPortException, PortInUseException, UnsupportedCommOperationException {
throw new RuntimeException("stub");
}
