Blinking Tray Icon
there no issue to change Icon on some bases with output as blinking Icon
create an
Arrays of BufferedImageor Queuestart Swing Timer on desired event and change
BufferedImageor Icons on some periodand to stop
Swing Timerafter some time remained or addActionListenerto theMessage, another way could be determineLEFTorRIGHTmouse button fromMouseListener( forIconinSystem Tray) one for stop ofTimer, second forJPopup
EDIT
for example, as I mentioned you can add ActionListener or MouseListener, there you can to stop Swing Timer
