Step to Reproduce:
--------------------
1) Run the attached program. You will see a Frame on the screen & a tray icon is added to the system tray.
2) Click on the 'Display Message' button. You can see ballon on the TrayIcon. Observe that there should be a tab in the title of the ballon between 'Application' & 'State'. In the same way observe in the message part "This is a message test" shoud come in the first line & "Ballon can't display Escape character" should come in the second line. But this is not coming as expected.

This work fine in window, but fails in solaris & RHEL.
