Java : Audio capture device listing using Java Media Framework

Question

import javax.media.*;
import java.util.*;

public class ListCaptureDevices {

    public static void main(String[] args) {

        Vector info = CaptureDeviceManager.getDeviceList(null);
        if (info == null)
            System.out.println("No Capture devices known to JMF");
        else {
            System.out.println("The following " + info.size()
                    + " capture devices are known to the JMF");
            for (int i = 0; i < info.size(); i++)
                System.out
                        .println("\t" + (CaptureDeviceInfo) info.elementAt(i));
        }
    }
}

Above is the code to list the capture devices. It does not return null vector but still it print the size of the vector as 0 and says no devices are found. What is wrong with this code?

It is not necessary to use JMF to discover the sound capture devices. See the MediaTypes class on this answer for example source.
