Comments on: Finally Pinned Down my Java Issue http://fschiettecatte.wordpress.com/2008/10/29/finally-pinned-down-my-java-issue/ Thoughts from the edge of the 'net Sun, 13 Dec 2009 20:49:21 +0000 http://wordpress.com/ hourly 1 By: François Schiettecatte http://fschiettecatte.wordpress.com/2008/10/29/finally-pinned-down-my-java-issue/#comment-4291 François Schiettecatte Wed, 29 Oct 2008 23:04:17 +0000 http://fschiettecatte.wordpress.com/?p=746#comment-4291 Thanks. Actually I have been tracking this down for a while and the two people I showed it to had no idea (in their defense I think they probably discounted my making such a mistake.) I am glad I was able to solve it in the end, can't think what Sun was thinking putting that in the URL class. I have checked other places where I used URL Sets and changed that. Thanks.

I should have recognized this when I read your blog post. I could have saved you some time and frustration. Sorry. The java.net.URL problem is well-known. Basically you should never use it as a key in a collection, because its equals() and hashCode() functions are too slow to be useful. Workarounds include using the URI class, which is nice and fast, or a String like you noted. Oh man! I should have recognized this when I read your blog post.
