Tibor Digana updated SUREFIRE-1302:
-----------------------------------
I plan to send PING from Maven process every second. This would be better
synchronization.
The measurements show me that Full GC is determined my the amount of
committed memory.
If it is <= 512 MB the pause takes 1.2 second. Huge amount 4GB takes over
12 seconds to Full GC.
I would like to kill JVM after 10 seconds of idle PING if Xmx is <= 512m.
Otherwise 20 seconds.
If this is not satisfying our needs, we have to configure it via a new
configuration parameter.
If you are facing better algorithm, let me know.

> 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.
