java - Failsafe 插件在 CI 上随机崩溃

Question

我正在使用CircleCI在多模块应用程序中运行 Maven 测试。有一些针对 servlet 的集成测试是从本地 Jetty 服务器开始的。这些测试有时仅在 CI 上随机崩溃（在本地机器和其他开发人员机器上都可以），错误是：

Please refer to /root/project/project-name/target/failsafe-reports for the individual test results.
Please refer to dump files (if any exist) [date].dump, [date]-jvmRun[N].dump and [date].dumpstream.

崩溃后我找到了dumpstream文件./project-name/target/failsafe-reports/2019-12-10T08-45-37_373.dumpstream：

# Created at 2019-12-10T08:46:59.803

Java版本是：

openjdk version "1.8.0_232-ea"
OpenJDK Runtime Environment (build 1.8.0_232-ea-8u232-b09-0ubuntu1-b09)
OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)

我试图应用这个类似的答案：https ://stackoverflow.com/a/33757854/1723695 但它在这里不相关，因为MaxPermSize选项已过时并且在 Java8 中将被忽略，并且工作机器有足够的内存来运行测试（测试不会消耗很多内存，8Gb绰绰有余）：

$ java -XX:+PrintFlagsFinal -version | grep -i maxheapsize
uintx MaxHeapSize              := 18440257536        {product}

故障安全插件配置pom.xml为：

        <plugin>
          <artifactId>maven-failsafe-plugin</artifactId>
          <groupId>org.apache.maven.plugins</groupId>
          <version>3.0.0-M3</version>
          <configuration>
            <failIfNoSpecifiedTests>false</failIfNoSpecifiedTests>
            <runOrder>random</runOrder>
            <trimStackTrace>false</trimStackTrace>
            <systemPropertyVariables>
              <!-- some props for tests -->
            </systemPropertyVariables>
          </configuration>
        </plugin>

失败的测试总是不同的，我没有看到同一个测试失败了两次。
