Description
We use a custom DIC based on ContainerBuilder in one of our projects. Our Kernel overwrites the getContainerBaseClass in order to make sure this DIC is used instead of Container. As of Symfony 2.8.10 this is broken due to symfony/dependency-injection@e0eeba7#diff-7f4e44bf5b03bfea768fbd537f88c20bR147
Reproduction code:
composer.json
{
"require": {
"symfony/dependency-injection": "2.8.10",
"symfony/http-kernel": "2.8.10",
"symfony/config": "2.8.10"
},
"autoload": {
"classmap": [
"src/"
]
}
}src/Kernel.php
<?php
use Symfony\Component\Config\Loader\LoaderInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\Kernel as BaseKernel;
class Kernel extends BaseKernel
{
public function registerBundles()
{
return [];
}
public function registerContainerConfiguration(LoaderInterface $loader)
{
}
protected function getContainerBaseClass()
{
return ContainerBuilder::class;
}
}src/issue.php
<?php
require 'vendor/autoload.php';
$kernel = new Kernel('test', true);
$kernel->boot();Result:

thrown in vendor/symfony/dependency-injection/ContainerBuilder.php on line 396The solution could be to extend from Container instead of ContainerBuilder, but at this time I don't yet know it that has any other consequences.
