Infinite recursion when requesting application/vnc.api+json data [DATAREST-767]

Gabriel Bauman opened DATAREST-767 and commented

I have a test Spring Boot application with a single entity Contact and CrudRepository at /contact. There are no entity relationships.

When there are no entities in the database, the request:

curl 'http://localhost:8080/contacts' -H 'Accept: application/vnd.api+json'

Returns:

{
  "links" : [ {
    "rel" : "self",
    "href" : "http://localhost:8080/contacts"
  }, {
    "rel" : "profile",
    "href" : "http://localhost:8080/profile/contacts"
  } ],
  "content" : [ {
    "collectionValue" : true,
    "rel" : null,
    "relTargetType" : "sdr.Contact",
    "value" : [ ]
  } ]
}

But, when I add a record to the database, the same curl request is infinitely recursive:

{
  "links" : [ {
    "rel" : "self",
    "href" : "http://localhost:8080/contacts"
  }, {
    "rel" : "profile",
    "href" : "http://localhost:8080/profile/contacts"
  } ],
  "content" : [ {
    "id" : 1,
    "firstName" : "Test",
    "lastName" : "Person",
    "embeddeds" : {
      "content" : [ ]
    },
    "propertyAccessor" : {
      "bean" : {
        "id" : 1,
        "firstName" : "Test",
        "lastName" : "Person"
      }
    },
    "persistentEntity" : {
      "idProperty" : {
