I'm new in OSGi. I wrote JIRA plugin which is Apache Felix Bundle. My bundle uses Sprring Framework RestTemplate and Jackson XML for a simple REST API call.
So I use other bundle (available on OSGi containter) : Apache ServiceMix :: Bundles :: spring-web which has <Import-Package> set to com.fasterxml.jackson.*; version="[2,3)";resolution:="optional"
I installed jackson-databind, jackson-core and jackson-annotations (all in version 2.6.5) on OSGi container to provide missing, optional dependencies.
Full source code available on my github.
When I install my plugin everything is ok, but during runtime I recieve error :

It looks like OSGi containter do not figure out that com.fasterxml.jackson.core is now available.
Apache ServiceMix :: Bundles :: spring-web?I hope someone could help me with this.
If your bundle has an optional import and you allow it to resolve without the import being wired to an exporter, then that situation will continue until you do a "refresh" operation. OSGi tries to leave bundle import/export wiring as static as possible, because it can be expensive to recalculate and it also forced bundles to restart.
So if you want OSGi to wire to the import that is now available, you need to refresh. This can be done in the Gogo shell by typing the refresh command.
