Describe the bug
The code below yields an exception:
Exception in thread "main" com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `UnwrappedTest$Foo` (although at least one Creator exists): no int/Int-argument constructor/factory method to deserialize from Number value (1)

Version Information
2.19.0
Reproduction
import java.io.IOException;
import com.fasterxml.jackson.annotation.JsonUnwrapped;
import com.fasterxml.jackson.databind.json.JsonMapper;
public class UnwrappedTest {
record Foo(int a, int b) {}
record Bar(@JsonUnwrapped Foo a, int c) {}
public static void main(String[] args) throws IOException {
var m = new JsonMapper();
var bar = m.writeValueAsString(new Bar(new Foo(1, 2), 3));
var b = m.readValue(bar, Bar.class);
System.err.println(b);
}
}Expected behavior
It should just work.
If Bar#a is renamed, eg. to foo, the code passes.
