> Problem: slow startup of bundles that use spring and spring-dm.
> When spring-dm starts spring application context, it puts a lot of objects that contain URL into set/map structures.
> URL.hashCode delegates call to handler. 
> URLHandlersBundleStreamHandler does not implement hashCode(URL u), but URLStreamHandler (parent) calls InetAddress.getByName(name) with bundle number. 
> This call is very slow and method URLStreamHandler.getHostAddress is synchronized.
> We have found that Equinox's handler org.eclipse.osgi.framework.internal.core.BundleResourceHandler overrides hashCode(URL u).
> Thread dump that demonstrates problem is attached.
