Why I can't detect annotations from a loaded java class?

I have a plugin within i want to access to the class list of my model package from my maven project. Until now i just did this to load the classes into the plugin :

try {
            runtimeClasspathElements = project.getRuntimeClasspathElements();

        } catch (DependencyResolutionRequiredException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        URL[] runtimeUrls = new URL[runtimeClasspathElements.size()];
        for (int i = 0; i < runtimeClasspathElements.size(); i++) {
          String element = (String) runtimeClasspathElements.get(i);
          try {
            runtimeUrls[i] = new File(element).toURI().toURL();
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

newLoader = new URLClassLoader(runtimeUrls,
      Thread.currentThread().getContextClassLoader());
      try {          class=newLoader.loadClass("com.pkl.bc.personnaldata.model.Personne");

    if(class!=null)
        System.out.println(class.getCanonicalName());
    } catch (ClassNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

here i can see the full name of my class.

System.out.println(class.getDeclaredFields());
System.out.println(class.isAnnotationPresent(EditColumn.class));
for (Field f : class.getDeclaredFields()) {

                EditColumn v = f.getAnnotation(EditColumn.class);
                if (v != null) {

                    System.out.println(v.tableName());
                    System.out.println(v.oldName());

                }

            }

but i don't get anything, here is the output :

[Ljava.lang.reflect.Field;@398f573b
false

I also tried to use refelctions

Reflections reflections = new Reflections("com.pkl.bc.personnaldata.model.Personne");

          Set<Field> annotated = reflections.getFieldsAnnotatedWith(Deprecated.class);

          System.out.println(annotated);

this give me an empty list. here is my annotation :

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.FIELD})
public @interface EditColumn {

    String oldName() default "";

    String newName() default "";

    String tableName() default "";
}
