> org.apache.harmony.awt.gl.font.FontManager loads 67 classes from regex.jar. 
> We can avoid this to re-write using of java.lang.String.replaceAll method in it, by using indexOf and substring instead of. Then no regex classes are loaded during the startup of the most of swing application . Speedup on SwingHelloWorld is ~1%.
