Classes from "com.sun.*" and "sun.*" packages should not be used Sonar issue for Jersey client

Question

I am using jersey client for rest calls. Imports for my code are:

import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;

Everything is working fine. I am using Sonar for checking my Code quality.

sonar is showing a major issue for:

Classes from "com.sun." and "sun." packages should not be used

Is this actually bad practice to use classes from sun?

If yes, what are the alternatives?

It's better to migrate to JAX-RS 2.0 client classes. Some refactoring would be necessary though. See the migration guide. For example, if you wrote like this before:

Client client = Client.create();
WebResource webResource = client.resource(restURL).path("myresource/{param}");
String result = webResource.pathParam("param", "value").get(String.class);

You should write now like this:

Client client = ClientFactory.newClient();
WebTarget target = client.target(restURL).path("myresource/{param}");
String result = target.pathParam("param", "value").get(String.class);
