Tibor Digana commented on SUREFIRE-1302:
----------------------------------------
[~elecharny]
When you open logs from every test, e.g. {{surefire-reports}}, do you see that
every test method went through?
I think the JVM sends 0x04 by ASCII when terminating, {{End of Transmission}}.
Please do not use version {{2.18.1}}.
I removed the call {{CommandReader#stop()}} in 2.20 when JVM is going to finish
in {{ForkedBooter}}.
Please confirm that version {{2.19.1}} works.
I found that stopping reader thread is useless due to JVM stops it on exit but
I could not imaging the stream would be corrupted this way. The change was done
in da7ff6aa25a72094705c24981afbf8294ac4b1dc on 28.03.2017.

> 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.
