This PR was merged into the 4.4 branch. Discussion ---------- Fix OPcache class preload requirement `container.dumper.inline_factories` As stated by @nicolas-grekas in symfony/symfony#32581 (comment) > With preloading, a single big file can, in theory, be similarly fast or faster. `container.dumper.inline_class_loader` With this parameter set to `true`, we'll do extra `include_once` for classes already preloaded by OPcache. Additionally, it can lead to warnings (cannot redeclare class) in classes that use `class_alias`, like https://github.com/FriendsOfSymfony/FOSHttpCacheBundle/blob/master/src/EventListener/InvalidationListener.php#L33 It's because this class already declared in preload, and PHP tries to declare it again after `include_once` in service getter.
