It appears that JButtons with a customized background color are not rendered
properly with the Ocean L&F.
To reproduce: start up Java2Demo with any recent nightly build containing the
new Ocean L&F. Click on the "Clipping" tab, and look at the toolbar for the
"Areas" demo (or any other panel in that tab). The selected button (e.g.
"nop") background color should be green, as it is with the venerable Steel
L&F, but the green background does not show up with the Ocean L&F.
