@JsonProperty unexpectedly required

[Human]

I have a JSON object with a boolean isFavorite field, like so (simplified, obviously):

{ "attributes": { "isFavorite": false }}

If my kotlin class for parsing this object has an un-annotated isFavorite field, like so:

var isFavorite: Boolean? = null

The resulting object's isFavorite field remains null. However, if I redundantly annotate it with @JsonProperty like so:

@JsonProperty("isFavorite") var isFavorite: Boolean? = null

it works as expected.

I have exactly the same issue. I have an object with a var isFavorite: Boolean that is not parsed at all. @Human trick worked but why is this happening?

This is related to how Jackson works and not to the lib.
