PropertyAccessor treats methods as properties and invokes them during serialization #62733
Description
Symfony version(s) affected
7.x.x
Description
When serializing an object with symfony/serializer, the PropertyAccess component incorrectly decides whether to read a public property or call a method with the same name.
If a class contains public readonly properties and also defines methods with identical names, the PropertyAccessor attempts to invoke the method instead of reading the property, which leads to a runtime error.
