$object =newclass() {publicstring$uninitialized;};$this->propertyAccessor->getValue($object,'uninitialized');

Expected

ThrowsUninitializedPropertyException with message "The property "class@anonymous::$uninitialized" is not readable because it is typed "string". You should initialize it or declare a default value instead.".

Actual

ThrowsError with message "Typed property class@anonymous::$publication must not be accessed before initialization".

Side efect

Form with data of an anonymous class instance cannot be created. This code throws "Typed property class@anonymous::$name must not be accessed before initialization":

// in controller$data =newclass() {publicstring$name;};$form =$this->createForm(SomeFormType::class,$data);

This works as expected:

// in controllerclass SomeClass {publicstring$name;};$data =newSomeClass;$form =$this->createForm(SomeFormType::class,$data);

No exception is thrown because PropertyPathAccessor catches UninitializedPropertyException and returns null instead.
