Hello, AWT Team. Please review the fix for the issue: https://bugs.openjdk.java.net/browse/JDK-8025585 The fix is available at: http://cr.openjdk.java.net/~pchelko/8025585/webrev.00/
The fix is needed for JFXPanel support. We need to redispatch MOUSEWHEEL messages to the window under mouse. In case of Popups in a JFXPanel the HWND belongs to a different tollkit, so we need to use ::SendMessage to redispatch the message. With best regards. Petr.
