osx - Java System Tray Icon on MacOS 10.7.4 not showing animated gif -

i'm trying animated gif appear in macos system tray using java. have png icons showing corretly, try , set icon animated gif (so can show spinning timer) goes blank , shows nothing in system menu tray.

according javadocs system tray class, setimage should automatically support animated images if given doesn't specify image format or else required animated icons in system tray.

does know how working?

chances problem cannot resolved java.awt.systemtray class. option have try jdic uses native code. frankly i'm not sure whether jdic project maintained anymore, quite hard find information on web...

in project of mine used jdic integrate system tray. can use starting point , libraries there, if can't find other resources.
