The MEDIUM_WEIGHT_POPUP and the LIGHT_WEIGHT_POPUP passed to the setPopupType are just a hints for the
popupFactory, both could be ignored. For example if tooltip will be shown
outside of the owner then the HW popup will be used(even if LW or MW were requested).
And to expose the PopupFactory.setPopupType() to the user the fix for JDK-8147521 was implemented,
it looks the same thing as the current bug:
