JavaFX SWT and Swing-Interopt

[Tom Schindl]

Hi,

I'm on Mac as well and just gave 8u181 a spin and see the same problem
(beside others eg the DropDown popup does not move with window).

Just to make sure: It is curcial to not only bring up the DropDown-List
but also open the Dialog-Window with the color-spectrum, ... .
