When \Neos\Flow\Security\Authorization\Privilege\Entity\Doctrine\EntityPrivilegeExpressionEvaluator::evaluate is executed and deprecations are part of the logged errors, this error occrus:

Creation of dynamic property Neos\Flow\Security\Authorization\Privilege\Entity\Doctrine\EntityPrivilegeExpressionEvaluator::$newExpressions is deprecated in /var/www/html/Data/Temporary/Production/SubContextBehat/Cache/Code/Flow_Object_Classes/Neos_Flow_Security_Authorization_Privilege_Entity_Doctrine_EntityPrivilegeExpressionEvaluator.php line 45

Expected Behavior

There is no deprecation error message.

Steps To Reproduce

No response

Environment

- Flow: 8.3
- PHP: 8.3

Anything else?

This problem is a regression of this commit.
The use of the property newExpressions was not renamed in the extending class.

The implementation of the code generation differs between extended and extending class. Since EntityPrivilegeExpressionEvaluator does not use the expression cache but instead checks the function existence directly, I think the line
$this->newExpressions[$functionName] = $functionDeclaration;
should be removed completely instead of renaming newExpressions to evaluatedExpressions.
