[JAVA] Correct field validation in list of elements

Description

I have generated class:

@Validated
public class SomeClass extends AnotherSomeClass implements Serializable {
  private static final long serialVersionUID = 1L;
  @JsonProperty("...")
  @Valid
  private List<Element> elements = null;
  ...
}

It uses as a request body for POST controller. When it try to send request to controller without one required field from Element class, I have an error like: "elements[0].someField doesnt exist". Could I validate entity instead of list of entities with swagger codegen? I want to have error like: "someField doesnt exist" without list name and index of the element. Could you provide code example for this?

Swagger-codegen version

0.19.0.2

Command line used for generation

swagger-codegen-maven-plugin 0.19.0.2

<configOptions>
                <sourceFolder>swagger</sourceFolder>
                <library>spring-mvc</library>
                <interfaceOnly>true</interfaceOnly>
                <useBeanValidation>true</useBeanValidation>
                <java8>true</java8>
                <serializableModel>true</serializableModel>
                <useTags>true</useTags>
</configOptions>

The report identifies generated SomeClass and Element models, a Spring MVC POST body, and the useBeanValidation configuration in the Maven plugin. Reproduce the missing Element.someField request with swagger-codegen 0.19.0.2, then inspect the generated validation behavior; done requires a documented or tested expected error path, but no repository file or test is named.
