title: Rest Assured java.util.HashMap cannot be cast to class java.util.List
body: <p>I am working on Rest assured framework to automate API testing. actually  I want to get the response as list not as an object. cause I want to do assertions for each element. to check data integrity for each element. I am executing this code:</p>
  
  <pre><code>    List&lt;Category&gt; categories = given().
              headers(
                      "Authorization",
                      "Bearer key",
                      "Content-Type",
                      ContentType.JSON,
                      "Accept",
                      ContentType.JSON)
              .when()
              .get("/rest/V1/categories").then().extract().response().jsonPath().getList("", Category.class);
