Infinite recursion when HTTP header is Accept:application/vnd+json [DATAREST-734]

Hi there,
In STS, I follow menu File/New/Import Getting Started Content, choose project Accessing Data Rest, then click Finish.
Then I run the gs-accessing-data-rest-complete project, and add(POST) one record to the people. When I send to the server with request as follow:

GET /people HTTP/1.1
Host: localhost:8080
Content-Type: application/json;charset=UTF-8
*Accept: application/vnd+json*
Cache-Control: no-cache

the server come into Infinite recursion and report these exception:

at com.fasterxml.jackson.databind.ser.BeanPropertyWriter.serializeAsField(BeanPropertyWriter.java:693) ~[jackson-databind-2.6.4.jar:2.6.4]
at com.fasterxml.jackson.databind.ser.std.BeanSerializerBase.serializeFields(BeanSerializerBase.java:675) ~[jackson-databind-2.6.4.jar:2.6.4].

I debug into the BeanPropertyWriter and BeanSerializerBase, and get the content of output buffer of the JsonGenerator, as follow:

  "links" : [ {
    "rel" : "self",
    "href" : "http://localhost:8080/people"
  }, {
    "rel" : "profile",

  }, {
    "rel" : "search",
    "href" : "http://localhost:8080/people/search"
  } ],
  "content" : [ {
    "firstName" : "John",
    "lastName" : "Smith",
    "embeddeds" : {
      "content" : [ ]
    },

      }
    },
    "persistentEntity" : {
      "idProperty" : {

          "annotations" : [ { }, { } ],
          "declaredAnnotations" : [ { }, { } ],
          "synthetic" : false,
          "declaringClass" : "hello.Person",
          "enumConstant" : false,
          "genericType" : "long",
          "accessible" : true
        },

        "owner" : {

              "synthetic" : false,
              "declaringClass" : "hello.Person",
              "enumConstant" : false,
              "genericType" : "long",
              "accessible" : true
            },
            "association" : false,
            "owner" : {
              "idProperty" : {
                "name" : "id",
                "rawType" : "long",
                "field" : {
                  "name" : "id",
                  "type" : "long",
                  "modifiers" : 2,
                  "annotations" : [ { }, { } ],
                  "declaredAnnotations" : [ { }, { } ],
                  "synthetic" : false,
                  "declaringClass" : "hello.Person",
                  "enumConstant" : false,
                  "genericType" : "long",
                  "accessible" : true
                },
                "association" : false,
                "owner" : {
                  "idProperty" : {
                    "name" : "id",
                    "rawType" : "lon...

It looks like the IdProperty take itself as its owner, I guess.

BTW, it goes well when use Accept: application/hal+json

thanks & regards
