Can't set background color for Java frame in Safari

Bug ID# 6297486

Under OS 10.5, setting a background color for a frame works using Firefox 2 but not Firefox 3.  However, it doesn't work using Safari, where a frame gets a very dark gray background.  This is illustrated using the frame that pops up from the applet on this page. 

Is this a bug?  Is there some way of setting the background color in a Java frame in Safari?

A workaround is to add a panel with the desired background color, as illustrated at this link.

If you have any insights, workarounds or comments about this test page please contact Mickey Segal.  A listing of  many Java resources is at this link.
