See http://michaelscharf.blogspot.com/2006/11/javaneturlequals-and-hashcode-make.html for more information. Consider using java.net.URI instead. 2483 1 gouessej 2013-04-16 10:30:20 +0200 In which classes do we use URLs except TextureIO & AWTTextureIO? 2643 2 sgothel 2013-06-09 08:57:15 +0200 GlueGen: IOUtil, JarUtil, TempJarCache, .. uses URI instead of URL to remove DNS Lookups etc . I have not seen further URL usage w/ equals/hash, which could trigger a DNS lookup. If anybody finds those .. pls reopen and report.
