java - Deserializing cyclic JSON with only one class involved with Jackson -

is possible deserialize following class jackson?

so original version of question wasn't entirely accurate. here's minimal example reproduce problem.

import java.io.ioexception;  import com.fasterxml.jackson.annotation.jsoncreator; import com.fasterxml.jackson.annotation.jsonidentityinfo; import com.fasterxml.jackson.annotation.jsonproperty; import com.fasterxml.jackson.annotation.objectidgenerators; import com.fasterxml.jackson.databind.objectmapper;  @jsonidentityinfo(   generator = objectidgenerators.intsequencegenerator.class,   property = "id") public class thing {    public thing thing;    @jsoncreator   public thing(@jsonproperty("thing") thing thing) {     this.thing = thing;   }    public static void main(string[] args) throws ioexception {     objectmapper mapper = new objectmapper();      thing cyclic = new thing(null);     cyclic.thing = cyclic;      string serialised = mapper.writevalueasstring(cyclic);     system.out.println(serialised);      thing deserialised = mapper.readerfor(thing.class).readvalue(serialised);     system.out.println(deserialised.thing == deserialised);   } } 

this causes unresolved forward reference exception. issue seems jackson told use annotated constructor, can't due cyclic dependency.

the solution add default constructor, , remove @jsonproperty , @jsoncreator annotations.
