我正在做一个相当复杂的java项目，它有许多依赖项和许多单元测试。

我在mac (mavericks)上使用java 1.6.0_65 (Mavericks)和maven 3.0.5，maven-surefire-plugin:2.16在几个分支中运行。我的问题是，使用多个fork运行此设置会导致fork退出，并显示以下内容：

“派生的VM在没有正确说再见的情况下终止。VM崩溃或System.exit调用?”

只使用一个fork来运行它不会产生问题(并且一切都会通过)

有一些关于这个问题的信息，包括this StackOverflow question和this surefire bug (现在似乎已经解决了)

我意识到这种情况的“答案”是在我的代码中找到调用System.exit()的东西--我找不到任何东西。

或者是什么原因导致我的JVM崩溃--没有hs_pid崩溃报告。

我的问题是，我可以使用什么样的策略来找到这个原因？澄清一下，我对上面提到的答案不感兴趣，而是一种找到它起源的方法。(或者更好的是，对可能导致这种情况的原因有一个完全不同的答案)

我确定的配置是：(但我确实尝试了其他组合)

代码语言：javascript

<parallel>classes</parallel>
<threadCount>1</threadCount>
<forkCount>1C</forkCount>
<reuseForks>false</reuseForks>
<useSystemClassLoader>false</useSystemClassLoader>
<useManifestOnlyJar>true</useManifestOnlyJar>
<useFile>true</useFile>
<redirectTestOutputToFile>true</redirectTestOutputToFile>
<runOrder>alphabetical</runOrder>

更新#1调试在使用-- (-X)运行maven目标之后添加了相关的输出

步骤：

(1)使用-e和-X选项运行mvn以获取更多调试信息。

(2)在输出中查找"Error“。在我的例子中，当我运行mvn命令时，输出的一部分包括：

代码语言：javascript
复制
[ERROR] Command wascmd.exe /X /C "C:\dev\dev-tools\.....

(3)直接在命令shell中执行有问题的命令。

在我的例子中，执行

代码语言：javascript
复制
cmd.exe /X /C "C:\dev\dev-tools\....

从命令行产生了OutOfMemoryError。

在我的例子中，maven-surefire- forkedProcessExitTimeoutInSeconds的配置插件很有帮助。默认值是value maven-surefire-plugin:2.20.130秒。我的项目进行了非常耗时的测试，所以分叉的JVM发生了冲突。使用以下属性配置pom中的插件即可解决此问题。

代码语言：javascript
复制
<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
                <forkedProcessExitTimeoutInSeconds>120</forkedProcessExitTimeoutInSeconds>
        </configuration>
</plugin>

在这里写下我用来帮助其他被这个问题困扰的人的策略。

在调用System.exit()时，可以利用SecurityManager抛出异常。然后，您可以检查堆栈跟踪以查看是谁调用了exit()。如果对exit的调用是从隐藏在您所依赖的某个jars中的代码中发出的，而不是从您自己的代码中发出的，则这一点尤其有用。

代码语言：javascript
复制
private static void forbidSystemExitCall() {
    final SecurityManager securityManager = new SecurityManager() {
        public void checkPermission( Permission permission ) {
            if( permission.getName().startsWith("exitVM") ) {
                throw new RuntimeException("Something called exit ") ;
            }
        }
    } ;
    System.setSecurityManager( securityManager ) ;
}
