Selenium代码在localhost上工作正常，但无法捕获Jenkins上的StaleElementReourceExc0019

Question

代码：

try {
  driver.findElement(By.xpath("//div/table[@class='v-table-table']/descendant::tr/td[3])").click();
} catch(StaleElementReferenceException e) {
   // some code
}

这段代码在本地运行良好，异常由catch块处理，我的代码继续执行，但当我在Jenkins上运行相同的代码时，catch块无法捕获异常。

Found Element By : By.xpath: //div/table[@class='v-table-table']/descendant::tr/td[1]

日志：

Exception occured: org.openqa.selenium.StaleElementReferenceException: The element reference of <td class="v-table-cell-content"> is stale; either the element is no longer attached to the DOM, it is not in the current frame context, or the document has been refreshed

您的java.version:'1.8.0_151'太旧了。

将JDK更新到当前级别JDK 8u311并执行测试。

stacktrace错误还提到：

[GC (Allocation Failure)  56810K->10231K(139776K), 0.0097259 secs]

GC（分配失败）是GC循环启动的效果。

分配失败意味着没有更多的空间留给分配对象。旧的JVM没有打印气相色谱，原因是气相色谱循环较小。分配失败几乎是轻微GC的唯一可能原因。次要GC踢的另一个原因可能是CMS注释阶段（如果启用了XX： ScavengeBeforeRemark）。
