Bertrand Delacretaz commented on SLING-2570:
--------------------------------------------

Note that in testing SLING-2567 I noticed that the installer.core bundle was 
affected by updating a bundle to which the installer is wired by a 
DynamicImport-Package clause - I don't know enough about the wiring API so far 
to know if that will help in that case.

This will probably go away with SLING-2568, as it's the javax.servlet package 
which is dynamically imported and that will go away - but I'm still wondering 
if this method of detecting that the installer will be stopped when certain 
bundles are refreshed is reliable - also considering that in my case this 
happens at startup in a system upgrade, while many bundles are being 
started/updated/replaced.

> Recently support has been built into the OSGi installer to check whether 
> update of bundles affects the Installer bundle itself (for wiring reasons). 
> This is currently implemented using the deprecated PackageAdmin service.
> For newer platforms where the OSGi Wiring API is available, the newer API 
> should be used for that check. This makes our code simpler and cleaner.
