Summary

Internal deprecation leak.

Current behavior

We're seeing internal deprecations to doctrine:

context_exception_message
User Deprecated: Access to ClassMetadata::$reflFields is deprecated and will be removed in Doctrine ORM 4.0. (LegacyReflectionFields.php:59 called by ClassMetadata.php:599, https://github.com/doctrine/orm/pull/11659, package doctrine/orm)

context_exception_trace
vendor/doctrine/deprecations/src/Deprecation.php:108
vendor/doctrine/orm/src/Mapping/LegacyReflectionFields.php:59
vendor/doctrine/orm/src/Mapping/ClassMetadata.php:599

Expected behavior

no deprecation

How to reproduce

[greg0ire]

Is the trace truncated? What is calling ClassMetadata::getReflectionProperty()?

OK, I think I know what's wrong: we don't need fewer deprecations, we need more. In this case,we need to indicate to Gedmo that it needs to migrate to getPropertyAccessor.
