Karl Pauls commented on FELIX-3262:
-----------------------------------
I think what we need to do is to override getHostAddress and return null there.
The bundle url doesn't really have one.
I'll commited a fix for this, can your verify and close this issue if it works
for you?

> Environment: Karaf 2.2.3 with spring-dm, spring
> Reporter: Sergey Epik

> 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.
