[jira] Commented: (FELIX-1435) Resolver does not always resolve a
dynamic import to a fragment export
[ https://issues.apache.org/jira/browse/FELIX-1435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12737598#action_12737598 ]
Richard S. Hall commented on FELIX-1435:
----------------------------------------
I have committed a fix for this, but I am not completely happy with it. It attempts to merge fragments before seeing if it is even necessary (i.e., if the bundle has any dynamic imports). I could simply check to see if it is needed, but this check already happens internally in the resolver, so it seems like duplication of effort. I need to think about this some more.

> Packages exported by fragments are not always seen by bundles dynamically importing them. For example, consider the following scenario:
> Bundle A dynamically imports some package foo and is resolved, but no other bundles are present. Now a host and fragment are installed (but not resolved) where the fragment exports package foo. If A tries to access a class in foo, it will not get dynamically wired to the package, since the host/fragment pair will not be resolved.
> If the host/fragment pair were installed prior to A being resolved, it does work, but this is more by accident than design. We need to explicitly attempt to resolve fragments during dynamic import resolution.
