Shutdown not called properly

[brutto]

I'lls try to use this library without global instances, so i ll use sdk helper like below (mostly for auto shutdown)

$spanExporter = new SpanExporter(
    (new StreamTransportFactory())->create('php://stdout', 'application/json')
);
$spanProcessor =  BatchSpanProcessor::builder($spanExporter)->build();
$tracerProvider = TracerProvider::builder()
    ->addSpanProcessor(
        $spanProcessor
    )
    ->setResource($resource)
    ->setSampler(new ParentBased(new AlwaysOnSampler()))
    ->build();

$sdk = Sdk::builder()
    ->setTracerProvider($tracerProvider)
    ->setAutoShutdown(true)
    ->build();

Then i use $tracerProvider in standart way

$spanContext = SpanContext::createFromRemoteParent($traceId, $spanId);

$tracer = $tracerProvider->getTracer('test-command');
$span1 = $tracer
    ->spanBuilder('execute1')
    ->addLink($spanContext)
    ->startSpan();

$span1->setStatus(StatusCode::STATUS_OK);

...

$scope = $span1->activate();
$span2 = $tracer
    ->spanBuilder('execute2')
    ->startSpan();

...

$span2->end();
$scope->detach();

$span1->end();

After script is normaly ended no any shutdown functions from providers are called.
But if i use sdk with this method

$sdk = Sdk::builder()
    ->setTracerProvider($tracerProvider)
    ->setAutoShutdown(true)
    ->buildAndRegisterGlobal();

At the end everything are called properly (shutdown method from providers are called).

Also simple register shutdown also called normally

register_shutdown_function([$tracerProvider, 'shutdown']);

Try to find whats the root problem and didnt catch it. =/

Resolved.
in my case try to register shutdown in Command::execute method (symfony/console package), but move it into Command::initialize method start register as expected.
