Konrad Windszus commented on SLING-6392:
----------------------------------------
This patch looks ok to me as well, except that I want the method {{transform}}
to explicitly log an error in case a duplicate resource url is being generated
(in case there is no id and multiple results or in case there is multiple times
the same id being used).
The only drawback of using the id as suffix is that he id is very often is long
(i.e. not a perfect match for a suffix) and duplicates part of the URL. But it
at least fulfills the necessary requirements for the URL to become unique.
> OSGi Installer: Symbolic name changes on a resource keeping the same URL are
> not supported

> After deploying bundle with symbolic name {{A}} to JCR location
> {{/apps/myapp/install/mybundle.jar}} or somewhere in the filesystem it is
> correctly being picked up by the JcrInstaller or FileInstaller and deployed
> in Apache Felix. Now the symbolic name has been changed to {{B}} and the
> updated JAR has been deployed to the same location in the JCR
> {{/apps/myapp/install/mybundle.jar}} or to the file system the updated bundle
> is not correctly deployed.
> The OSGI installer console exposes that both bundles {{A}} and {{B}} are in
> state {{Installed}} but the /system/console/bundle only shows bundle {{A}}
> but not {{B}}.
> It would actually be expected that {{A}} is uninstalled, while {{B}} is
> getting installed!
> Such a change can happen if you use the {{maven-bundle-plugin}} with a
> default configuration and you just change the groupId of the underlying maven
> project. That will not affect the finalName of the artifact (by default
> artifactId) but the symbolic name of the bundle (see
> http://felix.apache.org/documentation/subprojects/apache-felix-maven-bundle-plugin-bnd.html#default-behavior).
