Description

With fixing the caching of MethodReflection objects in #78915, there is an issue now which leads to a fatal error when trying to read the reflection properties of a MethodReflection object restored from cache.

Fatal error: ReflectionFunctionAbstract::getDocComment(): Internal error: Failed to retrieve the reflection object in /var/www/htdocs/typo3_src/typo3/sysext/extbase/Classes/Reflection/MethodReflection.php on line 120

When writing a MethodReflection object to cache, the object gets serialized. As serialize does not take care of virtual properties (such as the reflection properties), the reflection information gets lost. Trying to access reflection properties on an object resumed from cache causes the fatal error.

To fix the error it seems sufficient to call the reflection object's __toString() method before serializing it.
