Re: missing requirement [org.apache.karaf.features.core/4.0.5] osgi.wiring.package; filter:="(osgi.wiring.package=org.eclipse.equinox.region.management)

Hi all Karafians,

It turns out that this exception is something that can be thrown in response to some other problem. In my case, a uses constraint violation:

{root=Uses constraint violation. Unable to resolve resource utils.common [utils.common/3.1.0.BUILD-201609281517] because it is exposed to package 'rx' from resources io.reactivex.rxjava [io.reactivex.rxjava/1.1.0] and io.reactivex.rxjava-reactive-streams [io.reactivex.rxjava-reactive-streams/1.0.1] via two dependency chains.

I found this by breaking in the ResolverImpl and inspecting faultyResources, which contained the real error. I do not know why the true cause is hidden.

I’ve created a JIRA at KARAF-4750 - Installing a feature can result in an ResolutionException which incorrectly reports the underlying issue <https://issues.apache.org/jira/browse/KARAF-4750>.

Best, Dan.
