Tibor Digana commented on SUREFIRE-1302:
----------------------------------------

[~opeyrusse]
Sooner or later we will use sockets and not these standard output and input 
streams.
We have to provide the users with fallback.
Then this dump file would not contain GC logs because it will be found in 
{{target/surefire-reports/TEST-null.txt}}.

> Surefire does not wait long enough for the forked VM and assumes it to be dead

> 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.
