a bug of v1.4

[lixiaoxin1989]

I use CM4, ubuntu server 20.10 64 bit, wiringpi 2.60, pi4j 1.4.

Run the following code will cause the eth0 lost its ipv4 address, so the eth0 will not work untill reboot.

import com.pi4j.io.gpio.GpioController;
import com.pi4j.io.gpio.GpioFactory;
import com.pi4j.io.gpio.GpioPinDigitalOutput;
import com.pi4j.io.gpio.PinState;
import com.pi4j.io.gpio.RaspiPin;

GpioController gpio = GpioFactory.getInstance();
GpioPinDigitalOutput pin1 = gpio.provisionDigitalOutputPin(RaspiPin.GPIO_17, "", PinState.LOW);
pin1.high();

But it's OK if run as following:

import com.pi4j.wiringpi.Gpio;

Gpio.wiringPiSetup();
Gpio.pinMode(17, Gpio.OUTPUT);
Gpio.digitalWrite(17, 1);
