Bug 203274 [Forms] Border calculation in FormToolkit.initializeBorderStyle looks wrong
3.3 It has: // Check for Windows Classic. If not used, set the style to BORDER RGB rgb = colors.getSystemColor(SWT.COLOR_WIDGET_BACKGROUND); if (rgb.red != 212 && rgb.green != 208 && rgb.blue != 200) borderStyle = SWT.BORDER; If it's trying to see if the background is something other than (212, 208, 200), then the &&s should be ||s.
