Bug 51837 [Progress] Bad message in progress dialog
I20040210 I got a bogus message when running a pile of jobs. A progress dialog appeared that read: "The operation cannot proceed because it is blocked by a background" A background what? :)

return JFaceResources.getFontRegistry().get(fontName);

		Font defaultFont = control.getFont();
		control.setFont(cached);
		JFaceResources.getFontRegistry().put(
			fontName,
			defaultFont.getFontData());
		return defaultFont;
	}
