在线程“主”中获取错误异常java.lang.NullPointerException如何解决？

Question

在线程“主”中获取异常java.lang.NullPointerException 错误一次又一次，

我该怎么办？ 这是代码

私有静态最终字符串FIREFOX_OPTIONS = null;

@SuppressWarnings("deprecation")
public static void main(String[] args) throws InterruptedException {



    DesiredCapabilities capabilities = DesiredCapabilities.firefox();

    ProfilesIni init = new ProfilesIni();
    FirefoxProfile profile = init.getProfile("default");
    profile.setPreference("general.useragent.override","Mozilla/5.0 (Linux; Android 6.0.1; Nexus 6P Build/MMB29P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.83 Mobile Safari/537.36");



    FirefoxOptions options = new FirefoxOptions().setProfile(profile);

    capabilities.setCapability(FirefoxDriver.PROFILE, profile);
    options.addArguments("-private");
    options.addArguments("start-maximized");
    capabilities.setCapability(FirefoxOptions.FIREFOX_OPTIONS, options);

    System.setProperty("webdriver.gecko.driver","C:\\Users\\abc\\Downloads\\geckodriver.exe");




    WebDriver driver = null;
    while(true) {

        try {



            driver = new FirefoxDriver(capabilities);
            driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
