SystemTray not supported on Windows 10

问题

With Java 8 sdk, when I do

if (SystemTray.isSupported()) {
   logger.error("SystemTray IS supported");
} else {
    logger.error("SystemTray IS NOT supported");
}

Why SystemTray is not supported on Windows 10 ?

And what can I do to make it supported ?

Thanks

回答1:

You can set headless property from code too:

System.setProperty("java.awt.headless", "false");

I found the problem! My JVM was just starting in HeadLess mode!

I do not understand why... maybe because I do not have any GUI excepted this icon.

TO deactivate Headless mode, start the program with -Djava.awt.headless=false
