Java trycatch未捕获异常

2 周，2 日 Questions & Answers 1456

我有以下方法：

private void checkIfLoggedIn() {
  try{
    try {
      new WebDriverWait(driver, 10)
            .until(ExpectedConditions.visibilityOfElementLocated(
             By.cssSelector("a[href*='score']")));
    } 
    catch (WebDriverException e) {
    } 
    loggedInState = 2;
  }
  catch (TimeoutException e) {
    loggedInState = -1;
  }
}

简单地说，这种方法的工作是等待网页加载完登录的pa 并通过更改一个变量来让代码的其余部分知道。这段代码在绝大多数情况下都能完美工作，但是如果驱动程序在完成之前（被另一个线程）关闭，它就会崩溃。我完全同意代码停止——如果网页已经关闭，它很可能已经完成了任务（或者因为其他原因崩溃）。问题是错误日志（发布在下面）不会消失。为了捕捉任何可能的异常，我甚至尝试了catch (Exception e)这样广泛的方法，但crashlog不会消失。任何建议都将不胜感激

编辑：多亏了@jdigital，我发现代码实际上捕捉到了异常，但这被Selenium输出自己的异常所掩盖。任何关于如何让selenium停止输出错误的建议都将不胜感激
