Reflections getTypesAnnotatedWith() method not returning annotated class value

I have created a custom annotation as below:

@Retention(RetentionPolicy.RUNTIME) 
@Target(ElementType.TYPE)
public @interface Connection {
  String protocol();
}

and I have a couple of classes with this annotation as below:

@Connection(protocol = "p1")
public class Connection1 {
  public boolean isValidConnection(ConnectionVo connection) {
    System.out.print("p1");
  }
}

@Connection(protocol = "p2")
public class Connection2 {
  public boolean isValidConnection(ConnectionVo connection) {
    System.out.print("p2");
  }
}

I have a method which selects Connection 1 or Connection 2 isValidConnection() method using Reflection as below:

public void getConnectionProtocol(ConnectionVo connectionVo) throws Exception {
   Reflections reflections = new Reflections(Constants.CONNECTION_VALIDATOR_PKG);//package with Connection1 and Connection2 classes
   Set<Class<?>> connections =   reflections.getTypesAnnotatedWith(Connection.class);

   for (Class<?> connection : connections) {
      Connection request = connection.getAnnotation(Connection.class);
      System.out.print(request.protocol() == connectionVo.protocol);//connectionVo has field protocol with calues p1,p2 etc.
    }          
}

Now I am trying to write a unit test for the same. I am encountering a problem where reflections.getTypesAnnotatedWith(Connection.class) is just returning names of classes with @Connection annotation i.e., Connection1 and Connection2. How can I get the value that it has i.e., p1 and p2.
