I2P systray code in ../java/src is public domain. SysTray is really obsolete. It supports Windows and kde3 only. We only instantiate it on Windows. The java.awt.SystemTray classes added in Java 6 (and used by apps/desktopgui) are the way to go now. We could either rewrite this to use SystemTray, or switch to desktopgui.
