Subject [jira] [Commented] (FELIX-3587) Uses constraint violation due to framework extension bundle
Date Mon, 09 Jul 2012 19:31:35 GMT

    [ https://issues.apache.org/jira/browse/FELIX-3587?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13409767#comment-13409767

Richard S. Hall commented on FELIX-3587:
----------------------------------------

For system bundle extensions, I'm not sure if there is a case that matters where the resolver
won't detect a need for the fragment. Regardless, it makes the most sense to figure out how
to run this through the resolver to determine if attaching the fragment is possible since
trying to detect it requires knowing something about resolving anyway. All of this is more
complicated than what I can think about right now, but I agree that this is a real issue that
should ultimately be addressed.

> There seems to be an issue with framework extension bundle and I have not checked the
spec yet. Felix allows extension bundle to be attached at runtime, but that can sometimes
lead to uses constraint violation if a package exported by the framework extension is also
exported by some other regular bundle and that package from regular bundle is in use. A refreshPackages
solves the issue, but that seems to be putting the onus on user. Can the framework be smart
enough to not attach an extension bundle to host when it sees that an extension is exporting
a package which is already in use?
