I did not see the “jclouds.osgi.fragment” configured in any other poms, so I removed it and all of the Karaf tests pass now. ??
A bit of a shot in the dark, but could you try with
<jclouds.osgi.fragment>jclouds-core;bundle-version="[1.3,3)"</jclouds.osgi.fragment>? I wonder whether it was refusing to load jclouds-core now that we're up to 2.0.0-SNAPSHOT...
