Describe the bug

Hello,
While updating to spring boot 3.4.x I faced an issue related to the upgrade of jackson dependencies from 2.17.3 to 2.18.2
Deserialization is not working anymore for a class with 2 constructor, one with @JsonCreator annotation.

It fails with this exception:

Instantiation of [simple type, class User] value failed for JSON property fullName due to missing (therefore NULL) value for creator parameter fullName which is a non-nullable type
 at [Source: REDACTED (`StreamReadFeature.INCLUDE_SOURCE_IN_LOCATION` disabled); line: 6, column: 13] (through reference chain: User["fullName"])

It seems it take the wrong constructor, I also try with @JsonIgnore and @JsonCreator(mode=DISABLED) on the first constructor but it didn't help.
Any idea on how to solve this issue?

Version Information

2.18.2,2.18.3

Reproduction

Project with failing test can be found on this repo https://github.com/fabienfleureau/jackson-deserialization-issue/

I have defined this class:

class User(
    val age: Int,
    fullName: String,
) {
    var firstName: String = fullName.split(" ").first()
    var lastName: String = fullName.split(" ").last()

    fun fullName() = "$firstName $lastName"

    @JsonCreator
    constructor(): this(
        age = 0,
        fullName = "John Doe",
    )
}

and the json to deserialize looks like this:

            {
                "age": 25,
                "firstName": "Jane",
                "lastName": "Doe"
            }

Expected behavior

I expected to have a user deserialized having age set to 25, firstName set to Jane and lastName set to Doe

Additional context

No response

Is this Kotlin? If so bring it to https://github.com/FasterXML/jackson-module-kotlin

It does seem like a really odd example. The json does not relate to the constructors. Can't you add another constructor that takes "age", "firstName", "lastName"?

[fabienfleureau]

Yes it is kotlin. I will create an issue on the other project. -> FasterXML/jackson-module-kotlin#932

Let's say I can't modify the structure of the class for "legacy" reasons.

I could have transferred but looks like it's been re-created: closing this one.
