GraphicsEnvironment API does not detect dynamically attached graphics device

    Details

    • Subcomponent:
    • CPU:
      generic
    • OS:
      windows

      Description

      FULL PRODUCT VERSION :


      ADDITIONAL OS VERSION INFORMATION :
      Environment:
        OS:windows8.1 pro (both 32bit and 64bit)
        JRE:Java7u2(32bit) and later

      A DESCRIPTION OF THE PROBLEM :
      Description:
      GraphicsEnvironment API does not detect dynamically attached graphics device

      how to reproduce:

      1. start application under JNLP
      2. attach new graphics device
      3. can't obtain "currently" attached device through GraphicsEnvironemnt API

      It works fine on jre6/jre7u2 or earlier.

      Test Source Code:

      import java.awt.GraphicsConfiguration;
      import java.awt.GraphicsDevice;
      import java.awt.GraphicsEnvironment;
      import java.awt.Point;
      import java.io.BufferedReader;
      import java.io.IOException;
      import java.io.InputStreamReader;

      public class test {

      private static void getgdi() {

      GraphicsDevice[] devices = GraphicsEnvironment
      .getLocalGraphicsEnvironment().getScreenDevices();

      for (int i = 0; i < devices.length; i++) {
      GraphicsDevice aGraphicsDevice = devices[i];
      int intWidth = aGraphicsDevice.getDisplayMode().getWidth();
      int intHeight = aGraphicsDevice.getDisplayMode().getHeight();
      GraphicsConfiguration gc = aGraphicsDevice
      .getDefaultConfiguration();
      Point point = gc.getBounds().getLocation();
      System.out
      .printf("display: %d width %d height %d : posX %d posY %d \n",
      i, intWidth, intHeight, point.x, point.y);
      }
      }

      public static void main(String args[]) {
      try {
      while (true) {
      InputStreamReader isr = new InputStreamReader(System.in);
      BufferedReader br = new BufferedReader(isr);
      String buf = br.readLine();
      if (buf.equals("end"))
      break;
      getgdi();
      }
      } catch (IOException e) {
      e.printStackTrace();
      }
      System.out.println("get gdiinfo done");
      }
      }
