-------------------------------------------

Thanks Tim, I agree. Your patch seems to be more pretty.. And it gives the same result (removes regex and boost on HW). So, please, go ahead to commit it. As for '/' - sure, it's useless.

> When any class loads java.net.URL is used. However it loads ~60 classes from regex.jar. We can avoid this to re-write using of java.lang.String.matches method in net.URL, by using indexOf and substring instead of. Then no regex classes are loaded during the startup. Speedup on HelloWorld is ~7%.
