Tibor Digana commented on SUREFIRE-1433:
----------------------------------------
You think this is normal in a test method?
{{Runtime.getRuntime().halt(99);}}
and you expect that Maven process will know if forked vm executed {{kill -9}}?
You think that parent jvm process should get any notification from child
process killer and that this is somehow covered by Java Specification and that
Surefire should take care?
> rerunFailingTestsCount does not help with crashes

> Key: SUREFIRE-1433
> URL: https://issues.apache.org/jira/browse/SUREFIRE-1433
> Project: Maven Surefire
> Issue Type: Bug
> Components: process forking
> Affects Versions: 2.20.1
> Environment: Linux, Java 8u131, Maven 3.5.0
> Reporter: Jesse Glick
> Attachments: demo.zip

> I have a CI job running lots of very slow tests, and am using
> {{-Dsurefire.rerunFailingTestsCount=2 -Dmaven.test.failure.ignore
> -Dsurefire.timeout=7200 -DreuseForks=false -DforkCount=2}} to run Maven. It
> will typically run for about three hours, collecting a lot of passing tests,
> a few flaking tests with subsequent passes, and a few true failures. But then
> it will abruptly halt with the infamous
> {code:none}
> Failed to execute goal
> org.apache.maven.plugins:maven-surefire-plugin:2.19.1:test (default-test) on
> project ...: ExecutionException The forked VM terminated without properly
> saying goodbye. VM crash or System.exit called?
> {code}
> The timing is unpredictable but the build seems to usually fail this way;
> sometimes I get lucky and it runs through all the tests, taking a number of
> hours. Diagnosing the crash is not likely to be straightforward, and frankly
> I do not care much—I just want Surefire to try again. Yet the
> {{rerunFailingTestsCount}} flag does not accomplish this—it only retries
> normal failures.
> You can see this from running the attached project. While you might expect it
> to go through 100 runs of the test, some failing politely and some crashing,
> instead you see something like
> {code:none}
