> 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
> Assignee: Karl Pauls
> 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).
> Thread dump that demonstrates problem is attached.
