another example - https://travis-ci.org/checkstyle/checkstyle/jobs/228125793#L829

I tried to reproduce this on my local ubunutu - but it works fine for about 700 launches
command was:
$ time while mvn clean integration-test failsafe:verify -DargLine='-Duser.language=fi -Duser.country=FI'; do :; done

so might be related to Travis versions of java/maven or OS/hardware nuances.

My details:

$ mvn --version
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T08:41:47-08:00)
Maven home: /opt/maven/default
Java version: 1.8.0_121, vendor: Oracle Corporation
Java home: /opt/jdk1.8.0_121/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-101-generic", arch: "amd64", family: "unix"

it is become more noticeable after version bump for maven surefire plugin

Issue still happens on merge with master: https://travis-ci.org/checkstyle/checkstyle/jobs/228744792#L820
It also happened on non-Localized UT jobs (test and coverage): https://travis-ci.org/checkstyle/checkstyle/jobs/228744780#L821

Could it be an issue with one of the tests and the order they are running in?
All the links in issue were killed right after starting ConfigurationLoaderTest.

Edit:
Comparing https://travis-ci.org/checkstyle/checkstyle/jobs/228744780#L821 (bad run) to https://travis-ci.org/checkstyle/checkstyle/jobs/228744791#L806 (good run), order of tests is exactly the same and so are maven versions.

Oldest incident of this problem is: #4079 (comment)
Mar 23 2017

The forked VM terminated without properly saying goodbye.

Message is coming from https://github.com/apache/maven-surefire/blob/master/maven-surefire-common/src/main/java/org/apache/maven/plugin/surefire/booterclient/ForkStarter.java#L675 .

If issue is not related to version bump, we should upgrade to most recent, run as "mvn -X ...." And share logs with Apache team for advise

This one failed on code coverage and didn't end with ConfigurationLoaderTest but with AllChecksTest.

still a problem on latest jdk8 ..... looks like it is related to ConfigurationLoaderTest as it always in logs .... I will try to disable it for some time as experiment.

Attention: we already have it disabled for nondex - https://github.com/checkstyle/checkstyle/blob/master/.ci/travis/travis.sh#L9 so smth is wrong with test ......

still a problem on latest jdk8 ..... looks like it is related to ConfigurationLoaderTest as it always in logs .... I will try to disable it for some time as experiment.

Attention: we already have it disabled for nondex - https://github.com/checkstyle/checkstyle/blob/master/.ci/travis/travis.sh#L9 so smth is wrong with test ......

This may be a surefire issue.

https://issues.apache.org/jira/browse/SUREFIRE-910
http://maven.apache.org/surefire/maven-surefire-plugin/faq.html#vm-termination

Surefire does not support tests or any referenced libraries calling System.exit() at any time.

https://issues.apache.org/jira/browse/SUREFIRE-686

grepping through the source code I see myriads of System.exit calls
Since it is generally considered extremely bad practice to terminate the vm like that, I am closing this issue as won't fix.

If fix works, we have 2 more items to do to finish this Issue.

  1. we need to find way to move that arguments to command line of Travis commands as it Travis problem, comment should be extended to have a reference to issue that we are fixing
  2. We also need to restore ignored tests in localized launches

lets keep this in pom, to make it more stable on hardware of our contributors that use non US locale.

problem usage of argLine is found at #3110 (comment)
no ability to override it from command line if argLine defined in surefire configuration.

interesting approach is found at Alfresco/alfresco-sdk#298 (comment), I will try to use it.
