分叉VM在没有正确道别的情况下终止。VM崩溃或调用System.exit

Question

我使用的是geb spock maven，ubuntu上的surefire 2.22.0版。直到两周前，它还可以正常工作，但突然我发现forked虚拟机没有恰当地说再见就终止了。虚拟机崩溃或系统崩溃。你叫出口吗 错误。以下是我的配置：

Maven Version: Apache Maven 3.6.0 
Java version: openjdk version "1.8.0_181"
M3_HOME : /opt/maven

当我点击mvn-Dtest=“some test”test命令时，它会抛出以下错误：

ExecutionException The forked VM terminated without properly saying goodbye. VM crash or System.exit called?
Command was /bin/sh -c cd /home/web/workspace/Durgesh_Delete1 && /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java -jar /home/web/workspace/Durgesh_Delete1/target/surefire/surefirebooter1782527278200611298.jar /home/web/workspace/Durgesh_Delete1/target/surefire 2018-11-16T11-10-54_226-jvmRun3 surefire2754275980317815656tmp surefire_01299389042676135686tmp

请关注这个问题。谢啦

Answer 1

最后，我可以通过在surefire插件的配置标签下添加以下行来解决这个问题：

<configuration>
    <useSystemClassLoader>false</useSystemClassLoader>
    <threadCount>1</threadCount>
</configuration>

拉什比在上述评论中提出的解决方案中提到了这一点，不幸的是，没有人投票支持这个答案，因此很难找到答案。谢谢
