Api Platform v2.7 crashes when preloading is enabled

[Tib-z]

API Platform version(s) affected: 2.7.0, 2.7.1
(The issue comes from the deprecation handling, did not exist in 2.6, v3 could not test yet..)

Description
After upgrading to 2.7 (v2.7.0, v2.7.1) api-platform crashes on production where opcache.prelaod is enabled. On v2.6.8 worked fine.

How to reproduce

• Upgrade to v2.7.*
• Make sure opcache.preload is enabled. (I use the Symfony's default preload script);
  • opcache.preload_user=www-data
  • opcache.preload=/var/www/config/preload.php
• Open /api or any api-platform endpoint

+1 have a same problem on prod also opcache is enabled, api-platform/core v2.7.2
disabling opcache removes the problem
