java.lang.RuntimeException: Stub! in Android with Mockito

I have been looking on Google for this error, and most of
the answers I have found is to move junit dependence, to the top. Or use another mocking
framework. I already moved the dependence and still fails, and the whole project uses
mockito and powermock.

This is in
resume, the code.

package
            co.pack.session;

import
            com.google.gson.JsonObject;
import org.junit.Test;
import
            co.pack.Session.Organization;
import static
            org.junit.Assert.assertEquals;

public class TestOrganization
            {


@Test
public void testLoadJson()
            {
 JsonObject json = new JsonObject();

            json.addProperty("theme_color", "red");
 Organization organization = new
            Organization();


            organization.loadFromJson(json);

 assertEquals("red",
            Organization.getThemeColor());


            }
}

Implementation

public
            static void loadFromJson(JsonObject json) {
 Organization.name =
            json.has("name") ? json.get("name").getAsString() : "";
 Organization.image =
            json.has("image") ? json.get("image").getAsString() :
            "";



            printActualOrganization();
}

private static void
            printActualOrganization() {
 Log.i(TAG, "_name_ " + name);

            Log.i(TAG, "_image_ " +
            image);
}

It
fails on a Log
line

Log.i(TAG, "_name_ "
+ name);

And got
this

java.lang.RuntimeException:
Stub!

            co.mobico.session.TestOrganization.testLoadJson(TestOrganization.java:28)

Log
lines, never causes any error on my test, I don't know what is happening in this
case.
