Michael Osipov commented on SUREFIRE-1302:
------------------------------------------
To fully understand the issue: the tests or something else in the VM takes too
long and the forked VM is not able to respond because it is blocked. Surefire
assumes this VM to be dead, though still alive having a valid PID?
> The forked VM terminated without properly saying goodbye. VM crash or
> System.exit called?

> Key: SUREFIRE-1302
> URL: https://issues.apache.org/jira/browse/SUREFIRE-1302
> Project: Maven Surefire
> Issue Type: Bug
> Components: Maven Surefire Plugin
> Affects Versions: 2.19.1
> Reporter: Yuriy Zaplavnov
>
> This issue happens because surefire kills the forked container if it times
> out waiting for the 'ping'.
> In org.apache.maven.surefire.booter.ForkedBooter class there is hardcoded
> constant PING_TIMEOUT_IN_SECONDS = 20 which is used in the following method:
> {code}
> private static ScheduledFuture<?> listenToShutdownCommands( CommandReader
> reader )
> {
> reader.addShutdownListener( createExitHandler( reader ) );
> AtomicBoolean pingDone = new AtomicBoolean( true );
> reader.addNoopListener( createPingHandler( pingDone ) );
> return JVM_TERMINATOR.scheduleAtFixedRate( createPingJob( pingDone,
> reader ),
> 0,PING_TIMEOUT_IN_SECONDS,
> SECONDS );
> }
> {code}
> to create ScheduledFuture.
> In some of the cases the forked container might respond a bit later than it's
> expected and surefire kills it
> {code}
> private static Runnable createPingJob( final AtomicBoolean pingDone, final
> CommandReader reader )
> {
> return new Runnable()
> {
> public void run()
> {
> boolean hasPing = pingDone.getAndSet( false );
> if ( !hasPing )
> {
> exit( 1, KILL, reader, true );
> }
> }
> };
> }
> {code}
> As long as we need to terminate it anyway, It would be really helpful if the
> problem could be solved making the PING_TIMEOUT_IN_SECONDS configurable with
> the ability to specify the value from maven-surefire-plugin.
> It would help to configure this timeout based on needs and factors of the
> projects where surefire runs.
