Deserialized collection fields ignores @Serdeable.Deserializable(as = ...)

[oujesky]

Expected Behavior

When @Serdeable.Deserializable(as = X.class) is specified on a deserialized collection/map field, Instance of this type will be used for this field instead of the default one

Same behaviour should be observed with @JsonDeserialize(as = X.class) which is mentioned as supported in the documentation (https://micronaut-projects.github.io/micronaut-serialization/latest/guide/#jacksonAnnotations)

Jackson deserialization respects @JsonDeserialize(as = X.class) and constructs the field with the specified type.

Actual Behaviour

Default collection type is constructed for given field (i.e. ArrayList<X> for List<X> property, etc.) instead the specified type.

Steps To Reproduce

Example:

@Serdeable.Deserializable
record RecordWithList(
    @Serdeable.Deserializable(as = LinkedList.class) List<Integer> list
) {}

...

var result = objectMapper.readValue("{\"list\": [1, 2, 3]}"), RecordWithList.class);

result.list() instanceof LinkedList // false
result.list() instanceof ArrayList // true

The problem is captured in the reproducer in: https://github.com/oujesky/micronaut-serde-as-bug/blob/main/src/test/java/com/example/MicronautSerdeAsBugTest.java including comparison with Jackson (which passes).

Both testMicronautObjectMapperWithMicronautAnnotations and testMicronautObjectMapperWithJacksonAnnotations fails with Expecting actual to be an instance of: java.util.LinkedList but was instance of: java.util.ArrayList
