Integration of jaxb2-maven-plugin with JUnit4

I am trying to execute a simple JUnit test in order to marshall/unmarshall some data.

Here is the definition of the 'data' :

@XmlRootElement(name = "data")
@XmlAccessorType(XmlAccessType.FIELD)
public class Data {
 public Data(){}
 @XmlAttribute(name = "name")
 private String name = "name";
 public String getName(){return this.name;}
 public void setName(String name){this.name = name;}
}

The application works fine (I can marshall/unmarshall this object as XML)

But when I execute the test, I have the following error (the code in the test is exactly the same as it is in the application):

I can't understand why the application works but not the test. I guess there is something about the plugin scope defined in maven. Here is my pom.xml :

<dependencies>      
    <dependency>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>jaxb2-maven-plugin</artifactId>
        <version>2.2</version>
        <scope>test</scope>
    </dependency>

        <artifactId>jmockit</artifactId>
        <version>0.999</version>

    </dependency>

        <artifactId>junit</artifactId>

You shouldn't use the jaxb2-maven-plugin as dependency.

And you may have to add 

        <dependency>
            <groupId>com.sun.xml.bind</groupId>
            <artifactId>jaxb-core</artifactId>
            <version>2.2.11</version>
        </dependency>

Try to add to your dependencies:

<dependency>
    <groupId>com.sun.istack</groupId>
    <artifactId>istack-commons-runtime</artifactId>
    <version>2.22</version>
</dependency>
