Incorrect deserialization of inner object when using `@JsonUnwrapped`, with duplicate property

[Sild]

I suggest that there is a bug, if I define the same names for getters\setters name in Child and Root classes.
I have try to use @JsonIgnore on Root getters\setters to prevent double-serialize, but always get null in child object.

Example of my issue: https://github.com/Sild/jackson-deserialize-test/

We get null in Child.entity. But if we rename Root.getEntity() and Root.setEntity() method (to getChildEntity, for example), we get correct Child.entity value

What would the expected behavior here be, in case of duplicates?

[Sild]

I have tried to mark Root.getEntity() and Root.setEntity() as @JsonIgnor to prevent duplicates and it helped on serialize, so I expect to skip it on deserialize.

@Sild So you would expect child property entity to mask property entity that parent has. But while that works on serialization, when deserializing ignoral also applies to Child where it should not?
If so, yes, I agree, this is not optimal.

I just wanted to verify that I understand expected behavior correctly, thank you for clarification.

[Sild]

@cowtowncoder Yes,

But while that works on serialization, when deserializing ignoral also applies to Child where it should not?

That's exactly what I want.

One more, Parent has no property entity. But has methods getEntity() and setEntity() with the same name as Child to provide access to Child's property entity.

[cowtowncoder]

@Sild by having methods getEntity() and setEntity(), parent object does indeed have property "entity" -- whether there is a field with that name or not is irrelevant from property introspection perspective. Fields are not same as properties, although existence of a visible field does also indicate a property: but property is a logical concept.

@cowtowncoder Thanks for your explanation. Then let's focus on @JsonIgnore annotation in Parent object and its expected behaviour during serialize\deserialize.
