Mission Impossible: Java

This gist is just a friendly reminder, mostly for me, about stuff that just don't work in Java. I've spent some (lots of) precious hours trying make it work,

AWT, Swing

• java.awt.SystemTray with javax.swing.JPopupMenu
  • While not impossible, no matter how hard you try, it will never work on all platform properly. Just stick with the default, ugly one.
• Changing the font of java.awt.MenuItem
  • No matter what is your workaround, it won't work, if the peer does not implement it (at least on Windows) - here's the source. Or, here's the snippet:

  package sun.awt.windows;
  /* ... */
  class WMenuItemPeer extends WObjectPeer implements MenuItemPeer { 
      /* ... */
      // Needed for MenuComponentPeer.
      public void setFont(Font f) {
      }
  }
