Swing never grabs the pointer for a popup, so a click on the desktop or
another application is not seen and the menu stays up. The little window
the menu hangs off is focusable now and closes it when the focus goes
elsewhere, Escape closes it, and clicking the icon again toggles it.
Raising the window was ignored for the same reason it usually is: a
window manager refuses a raise from an application that does not have the
focus. The icon asks for _NET_ACTIVE_WINDOW instead — the request meant
for pagers and trays acting for the user — and falls back to Swing's
always-on-top shuffle when it cannot find the window. Windows are matched
by _NET_WM_PID and _NET_WM_NAME, since WM_NAME cannot carry the em dash
in our title.

The icon carries the badge the tree draws next to our own nickname on the
active server — idle, talking, away, commander, microphone or speakers
muted — and clicking it brings the window back to the front. Right click
offers "Show TS3J" and "Quit".
AWT's tray icon cannot be transparent on X11: the toolkit embeds a window
of the screen's default, opaque visual and fills it with a background
colour before drawing the image, so every icon sits in a box. Panels that
can show transparent icons advertise an ARGB visual instead, so the icon
is docked by hand over the system tray protocol, in that visual, with the
image put on the window premultiplied. AWT's own icon stays as the
fallback for everything else.
Two details a panel will not forgive: an icon that publishes no size
hints is allocated a one-pixel sliver, and docking is a request, so an
icon that is never adopted has to hand over to the fallback rather than
sit invisible.
