REGRESSION : Getting exception when stage is visible

I have a stage which contains a SwingSlider & a rectangle. When the stage is visible, the following exception is thrown. I am not setting any opacity , but still the exception show the "Error setting window opacity using AWTUtilities ". A similar kind of bug is filed where the stage is applied with transparency .
http://javafx-jira.kenai.com/browse/RT-3494

It works fine in franca,but fails in marina. Hence its a regression.
