Passing Class object containing HashMap> as instance variable to RESTService

Question

i have a POJO class BookType as:

package com.jersey.series.json.service;

import java.util.HashMap;
import java.util.Set;

public class BookType {

@Override
public String toString() {
    return "BookType [bookId=" + bookId + ", bookName=" + bookName + ", author=" + author + ", category=" + category
            + ", obj=" + obj + "]";
}

protected int bookId;
protected String bookName;
protected String author;
protected String category;
protected HashMap<String, Set<String>> obj = new HashMap<>();

public HashMap<String, Set<String>> getObj() {
    return obj;
}

public void setObj(HashMap<String, Set<String>> obj) {
    this.obj = obj;
}


public int getBookId() {
    return bookId;
}


public void setBookId(int value) {
    this.bookId = value;
}


public String getBookName() {
    return bookName;
}


public void setBookName(String value) {
    this.bookName = value;
}


public String getAuthor() {
    return author;
}


public void setAuthor(String value) {
    this.author = value;
}


public String getCategory() {
    return category;
}


public void setCategory(String value) {
    this.category = value;
}

}

And a rest Service :

 package com.jersey.series.json.service;


import javax.ws.rs.Consumes;
import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

@Path("/bookservice")
public class BookServiceImpl implements IBookService {



@POST
@Path("addbookandreturnjson")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public BookType saveAndReturnBookInfojson(BookType bookType) {

    return bookType;
}
}

i ma making this call using PostMan:

http://localhost:8080/Jersey-JSON-IO/rest/bookservice/addbookandreturnjson

this is my message body with type application Json

 {"bookId":5,"bookName":"abc","author":"saurabh","category":"Test","obj":{"1":["abc","xyz"]}}

Service is receiving everything correct except for the "obj" field where am i doing wrong or what i need to do.I am using Glassfish 4.1.1 as web container.Here is my pom.xml
