Felix Meschberger commented on FELIX-3733:
------------------------------------------
This issue is tracked by the OSGi alliance and the conclusion seems to be that
the CT (assuming the path to be relative to the descriptor's bundle) is
probably correct and an errata should be issued for the spec.
Hence the workaround implemented in Rev. 1401851 would be ok and still fall
back to behaviour supporting the original spec text.
One minor fix is to catch any exception thrown when accessing an inaccessible
URL and return null instead of just throwing.

> Key: FELIX-3733
> URL: https://issues.apache.org/jira/browse/FELIX-3733
> Project: Felix
> Issue Type: Task
> Components: Metatype Service, Specification compliance
> Affects Versions: metatype-1.0.4
> Reporter: Felix Meschberger
> Assignee: Felix Meschberger
> Fix For: metatype-1.0.6
>
>
> The Metatype Service specification states for the location value of the icon
> element (Table 105.1 in section 105.7.1):
> The resource is a URL. The base URL is assumed to be the XML file
> with the definition. I.e. if the XML is a resource in the JAR file, then
> this
> URL can reference another resource in that JAR file using a relative URL.
> Our current implementation takes this definition and uses the XML resource
> URL as the base URL to create the Icon URL.
> For example: If the icon resource path is "icon/sample.png" and the XML
> resource URL is "file://bundle-5/OSGI-INF/metatype/sample.xml" then the icon
> resource URL would be assumed to be
> "file://bundle-5/OSGI-INF/icon/sample.png".
> In contrast the current OSGi CT work-in-progress expects the URL to be
> relative to the defining bundle.
> It must be clarified which reading is correct.
