Thread dump that demonstrates problem.
> Startup delay due to URLHandlersBundleStreamHandler
> ----------------------------------------------------
>
> Key: FELIX-3262
> URL: https://issues.apache.org/jira/browse/FELIX-3262
> Project: Felix
> Issue Type: Improvement
> Components: Framework
> Affects Versions: framework-3.0.9
> Environment: Karaf 2.2.3 with spring-dm, spring
> Reporter: Sergey Epik
> Attachments: getHosts-osgiextender.txt
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> 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).
> Here is thread dump that demonstrates problem:
