Object distortion while passing from REST service to Spring app

I've got strange problem and I hope you will to help me to solve it.
I try to pass list of objects, where each object contains LocalDate parameter (JodaTime library) from test service to my controller.

This is method from my service. It returns list of objects. Look at the dates printed out in the loop.

@RequestMapping("/getListaRecept")
@ResponseBody
public ListaRecept sendAnswer(){
ListaRecept listaReceptFiltered = prescriptionCreator.createListaRecept();

for(Recepta r : listaReceptFiltered.getListaRecept()){
System.out.println(r.toString());
}
return listaReceptFiltered;
}


Dates are correct

Recepta{id=3, nazwa='nurofen', status=NOT_REALIZED, date=2017-07-27}
Recepta{id=1, nazwa='ibuprom', status=ANNULED, date=2014-12-25}
Recepta{id=2, nazwa='apap', status=REALIZED, date=2016-08-18}


And now I'm invoking this method from my SpringBoot app using restTemplate. And then received list is printed out

private final RestTemplate restTemplate;

public SgrService2(RestTemplateBuilder restTemplateBuilder) {
this.restTemplate = restTemplateBuilder.build();
this.restTemplate.getMessageConverters()
.add(0, new StringHttpMessageConverter(Charset.forName("UTF-16")));
}

public ListaRecept getList() {
for(Recepta r : this.restTemplate.getForObject("http://localhost:8090/getListaRecept",
ListaRecept.class).getListaRecept()){
System.out.println(r.toString());
}
return this.restTemplate.getForObject("http://localhost:8090/getListaRecept",
ListaRecept.class);
}


As you can see all dates were replaced with current date :/

Recepta{id=3, nazwa='nurofen', status=NOT_REALIZED, date=2017-09-30}
Recepta{id=1, nazwa='ibuprom', status=ANNULED, date=2017-09-30}
Recepta{id=2, nazwa='apap', status=REALIZED, date=2017-09-30}


I have no idea what is going on...
Here you have pom dependencies

<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time</artifactId>
<version>2.9.9</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-jsr310</artifactId>
<version>2.9.0</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.9.1</version>
</dependency>


Thank you in advance for your help

It seems to me that you are using the wrong jackson module, instead of jsr310 (which I guess is for Java 8 date types), try using the artifact jackson-datatype-joda and register the module JodaModule.
