ToolTip/JPopupMenu bug?

Question

The popup menu and tooltips for the menu items in the popup menu in my program had been working fine until I added a glassPane. Then I noticed that sometimes the popup menu is drawn below the glasspane and doesn't respond to the cursor moving over its menu items.
So I disabled its option to use a lightwight component.
Now, the popup menu is always drawn on top of glasspane and responds.
But . . . now
. . . sometimes, tooltips are drawn behind the popup menu!
Is there any simple fix for this problem?

The problem is inside the PopupFactory :
    private int getPopupType(Component owner, Component contents,
                             int ownerX, int ownerY) {
        int popupType = getPopupType();
     if (owner == null || invokerInHeavyWeightPopup(owner)) {
         popupType = HEAVY_WEIGHT_POPUP;
        else if (popupType == LIGHT_WEIGHT_POPUP &&
                 !(contents instanceof JToolTip) &&
                 !(contents instanceof JPopupMenu)) {
            popupType = MEDIUM_WEIGHT_POPUP;
     return popupType;
    }The weight of the ToolTip popup is determined by its parent -- in your case, the parent is a menuitem which is light-weight regardless of how you set the menuitem's owner (JMenu?). If you don't want to write your own ToolTipManager, you'll have to find a way to set the weight of the JMenuItems!
