Mode.PROPERTIES still does not support single argument constructor.

[hjohn]

I have a simple class:

public A {
    private final String title;

    public A(String title) {
        this.title = title;
    }
}

When I serialize this (with private field visibility) I get:

{
  "title" : "Alice in Wonderland",
}

When deserializing (with new ParameterNamesModule(Mode.PROPERTIES)) I however get this exception:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of A (although at least one Creator exists): cannot deserialize from Object value (no delegate- or property-based Creator)

What is ambigious here? There is a creator, but it refuses to use it, even though the properties are matches for the parameter names.

If I add a @JsonProperty annotation or a 2nd parameter, the ambiguity disappears. Is it really impossible to tell Jackson to never ever attempt deserializing by passing in a piece of JSON string text? I never want it to use Mode.DELEGATING...
