我正在开发一个相当复杂的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,使用maven 3.0.5和maven-surefire-plugin:2.16在几个forks中运行.我的问题是使用多个forks运行此设置会导致fork退出:
"分叉的虚拟机终止了,没有说再见.虚拟机崩溃或System.exit调用？"
只使用一个fork运行它不会产生问题(并且一切都通过)
有一些关于这个问题的信息包括这个StackOverflow问题和这个万无一失的bug(现在似乎已经解决了)
我知道这种情况的"答案"是在我的代码中找到什么叫System.exit() - 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.
我的问题是我可以用什么样的策略来找到找到这个原因的？ 为了澄清,我对上面提到的答案不感兴趣,但是找到它的起源.(或者甚至更好地回答可能造成这种情况的不同答案)
我的Surefire配置是:(但我确实尝试过其他组合)
<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>
在使用--debug(-X)运行maven目标后添加#1添加相关的输出

有没有人见过同样的事情？
