PATCH a collection throws exception [DATAREST-1041]

Petar Tahchiev opened DATAREST-1041 and commented

Hey guys,

I have the following setup:

public class CategoryEntity {
    @ManyToMany
    private Set<ProductEntitiy> products;
}

now I wrote a test-case that issues a PATCH request to update the collection like this:

mockMvc.perform(patch("http://localhost:8080/categoryEntities/1").content(
                "{ \"products\" : [\"http://localhost:8080/productEntities/1\"]}").accept(
                MediaType.APPLICATION_JSON_UTF8_VALUE).contentType(MediaType.APPLICATION_JSON_UTF8_VALUE)).andDo(print()).andExpect(
                status().isOk());

The results are the following:
Spring Boot 1.5.2.SNAPSHOT= Ingalls SR1 = X
Spring Boot 1.5.1.RELEASE = Ingalls REL = X
Spring Boot 1.5.0.RELEASE = Ingalls REL = X
Spring Boot 1.4.6-SNAPSHOT= Hopper SR8 = X
Spring Boot 1.4.5 RELEASE = Hopper SR8 = X
Spring Boot 1.4.4 RELEASE = Hopper SR7 = X
Spring Boot 1.4.3 RELEASE = Hopper SR6 = X
Spring Boot 1.4.2 RELEASE = Hopper SR5 = V
Spring Boot 1.4.1 RELEASE = Hopper SR3 = V
Spring Boot 1.4.0 RELEASE = Hopper SR2 = V
Spring Boot 1.3.8 RELEASE = Gosling SR5 = V

And every single time the exception is the same:

Body = {"cause":{"cause":null,"message":"Can not construct instance of com.example.ProductEntity: no String-argument constructor/factory method to deserialize from String value ('http://localhost:8080/productEntities/1')\n at [Source: N/A; line: -1, column: -1]"},"message":"Could not read payload!; nested exception is com.fasterxml.jackson.databind.JsonMappingException: Can not construct instance of com.example.ProductEntity: no String-argument constructor/factory method to deserialize from String value ('http://localhost:8080/productEntities/1')\n at [Source: N/A; line: -1, column: -1]"}

I have jackson-hibernate5 on the classpath. Also I remember not so long ago the body of the request was like the following:

{ "products" : [1]}

(just the ids not the local url) so I tried that one too, but it failed with all of the versions of spring boot.

I'll provide a test project
