Yes Jim. Per the current code base, it is defaulted to default screen.
To have the same tray icon being represented on multiple task bars would require updates to XSystemTrayPeer.java to replicate the message being sent to X11 to add a new tray icon for a particular screen(Currently it is done only for the default screen). The current X11 tray system uses XEMBED protocol to add system tray icons.
Currently the screen is set to 0 which I think would refer to default screen and hence it adds tray icons only to the default screen. The X11 property '_NET_SYSTEM_TRAY_S[SCREEN_NUMBER]' allows access to the system tray of screen 'SCREEN_ NUMBER '. So we may need to use such mechanism to add the tray icon onto different screens. This may be different for windows and mac but will have a similar mechanism.
Thanks and regards,

Will the tray icon canvas always be on the default screen? I believe the latest MacOS and Win10 both allow menu bars and task bars on all monitors. Linux may not be far behind...
