ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
By using the system tray icon demo application http://docs.oracle.com/javase/tutorial/uiswing/examples/misc/index.html#TrayIconDemo and modifing the title of a popup to : "TachoSafe RDU Manager - pro_drivers - Driver Card download Error"

like this :

                    trayIcon.displayMessage("TachoSafe RDU Manager - pro_drivers - Driver Card download Error",
                            "This is an error message", TrayIcon.MessageType.ERROR);


Java will freez.
I thought the problem could be that if i put more than 63 characters in the title, but no, or exactly 64 characters, but no.
