The constructor is not visible (but it is)

[Geoffrey De Smet]

Using gwt 2.8.0, restygwt 2.2.0, gwtjackson 0.14.2 (all latest versions),
I am getting this error:
  [ERROR] Line 22: The constructor Employee() is not visible
But that constructor is visible:

public class Employee implements Serializable {

    private String name;

    private Employee() {
    }

    public Employee(String name) {
        this.name = name;
    }
    ...
}

Any idea what can cause this?

Gwt jackson is trying to use the private constructor.
Add a @JsonProperty("name") to the public constructor name parameter then it should work. Why do you even declare a private default constructor ?

(My previous mail had a bad copy paste - the constructor is public.)

Even with a public no-arg constructor and a public @JsonProperty constructor as shown below,
I am getting that error "Line 22: The constructor Employee() is not visible":

public class Employee implements Serializable {

    private String name;

    public Employee() {
    }

    public Employee(@JsonProperty("name") String name) {
        this.name = name;
    }
...
}

That weird.
Could it be due to the use of the latest GWT and latest gwtjackson releases (gwt 2.8.0, restygwt 2.2.0, gwtjackson 0.14.2)?
