blocking java.net.URL methods

Hi!

I found a really interesting blog about the behaviour of URL#hashCode and URL#equals:

http://michaelscharf.blogspot.com/2006/11/javaneturlequals-and-hashcode-make.html

I'm programming Java since a long time but I actually wasn't aware that iterating over URLs _always_ performs DNS lookups  :(
And yes, we use URLs a lot in our code - but as far as I've seen only for jar and file resources (classpath URLs).

LieGrue,
