Hello all,
I am new to osgi in general so apologies in advance if I am not entirely
correct in the description of the issue I am facing. I started using the
aws-java-sdk/1.10.0_1 bundle in order to fetch some objects from s3, although
at runtime I am getting a class not found exception while using the standard
code path of the sdks on a dependency that should be imported by the
aws-java-sdk bundle.

Checking the pom.xml for aws-java-sdk/1.10.0_1 I can see that the dependecy on
com.fasterxml.jackson is declared as optional:
https://git-wip-us.apache.org/repos/asf?p=servicemix-bundles.git;a=blob_plain;f=aws-java-sdk-1.10.0/pom.xml
When installing a bundle such as the aws sdk, as a user I am expecting that
everything will be provided, is this assumption wrong when dealing with
third-party bundles?
As a workaround now I am explicitly specifying com.fasterxml.jackson.core as a
bundle in my karaf feature file, is this the correct way to deal with this?
I am a little bit worried about the maintainability of the feature file in case
using a lot of third-party library and keeping all their dependencies up to
date. What is your experience with that?
Thanks,
Federico
