[jira] Commented: (FELIX-758) Updated version of a module imports its old version's packages

["Richard S. Hall (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FELIX-758?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12638559#action_12638559 ] 

Richard S. Hall commented on FELIX-758:
---------------------------------------

Actually, we did put this into the R4.1 spec in section 4.3.10, where it explicitly states that the packages are available for future resolves. However, I will warn that this is still a discussion topic. I am pushing for the current interpretation.

> Hi all,
> In the OSGi specification R4.0.1, 
> "An updated bundle must directly provide its exported packages to the system.
> At the same time, packages exported by the previous version continue
> to be available, for existing and future bundles, until the refreshPackages
> method has been called or the Framework is restarted."
> It is not clear if the new version of the bundle has the right to import packages from its old version before the refresh is done. Anyway in Felix this happens: in certain cases the resolver creates wires such as 
> WIRE: 4.1 -> com.bugtest -> 4.0
> Is this a bug ?
> If this is not a bug, I apologize for the waste of time. 
> If this is a bug we could solve it easily by giving a higher ranking to the internal packages of the new bundle when creating the wire (e.g. this would create a 4.1 -> com.bugtest -> 4.1).
> Note : doing "stop" then "update" then "refresh" then "start" avoids the problem because in such case the old module is garbaged out.
> I have some bundles that reproduce this ; available via email at sylvainmarie2 - at - yahoo.fr .
> Cheers
> Sylvain
