Updated version of a module imports its old version's packages
--------------------------------------------------------------
Key: FELIX-758
URL: https://issues.apache.org/jira/browse/FELIX-758
Project: Felix
Issue Type: Bug
Components: Framework
Reporter: Sylvain MARIE
Priority: Minor
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

Cheers
Sylvain
