      Description

      This occurs only with b81 PIT build on Solaris and Linux platforms.

      I have a java program which adds a TrayIcon to the system tray and then removes it. The java process does not exit even after the TrayIcon is removed. Below is the java program I execute:

      import java.awt.*;
      import java.awt.image.BufferedImage;

      public class TrayIconTest {
          public static void main(String[] args) {
              try {
                  SystemTray st = SystemTray.getSystemTray();
                  BufferedImage image = new BufferedImage(16, 16, BufferedImage.TYPE_INT_ARGB);
                  Graphics gr = image.createGraphics();
                  gr.setColor(Color.white);
                  gr.fillRect(0, 0, 16, 16);
                  TrayIcon icon = new TrayIcon(image);
                  st.add(icon);
                  st.remove(icon);
              } catch (Exception e) {
                  e.printStackTrace();
              }
          }
      }

      Below is the threaddump when the process does not exit:
