<AWT Dev> [8] Request for review: JDK-8022512 JLightweightFrame: the content pane should be transparent

Hi Anton,

The fix looks good I suppose. However, are you sure we want to support 
transparent content in embedded components? I understand that it's cool 
and stuff, but do we have to? We don't support transparency for 
heavyweight embedded frames (e.g. applets), why would we want to support 
it for the JLF? How are you going to handle mouse events on transparent 
parts? Will JFXPanel support the same?

best regards,
