John Ross commented on ARIES-1452:
----------------------------------
Is this still an ongoing issue? The output seems strange because the two
referenced providers of org.osgi.framework appear to be the same object (i.e.
"[org.apache.felix.framework [0](R 0)]"), so how could there be a problem?
Something interesting is the first import wants version [1.5, 2.0) while the
second wants [1.3, 2.0), but if the provider is really the same, the exported
versions should be the same. Different versions (say one exporting at 1.3 and
the other at 1.5) would appear to imply that there must be two system bundles
involved, which seems unlikely.
Maybe subsystems is returning different objects to two separate findProviders
requests? One wrapped and one not?

> Project: Aries
> Issue Type: Bug
> Components: Subsystem
> Affects Versions: subsystem-2.0.6, subsystem-2.0.8
> Environment: Mac OS X
> Apache Felix (inside Apache Sling 9-SNAPSHOT)
> Reporter: Roy Teeuwen
> Attachments: testcase.zip

> When building an OSGi subsystem feature, I created two bundles, an api and a
> core. The core has following embedded dependency:
> <dependency>
> <groupId>com.squeakysand.osgi</groupId>
> <artifactId>squeakysand-osgi</artifactId>
> <version>0.4.0</version>
> </dependency>
> Using previous dependency in the core, it creates the Import-Package
> org.osgi.framework;version="[1.5,2)” when using maven-bundle-plugin version
> 3.0.1.
> Starting up this subsystem through the webconsole subsystem plugin of Apache
> Felix, following error is thrown:
