add-features-to-repo goal does not reclaim file handles fast enough

                 Key: KARAF-1216
                 URL: https://issues.apache.org/jira/browse/KARAF-1216
             Project: Karaf
          Issue Type: Bug
          Components: karaf-tooling
    Affects Versions: 2.2.5
            Reporter: Jonathan Anstey

For larger feature sets like for the ServiceMix Full distro, the number of file handles accumulated
can exceed the OS defaults on some systems. The culprit seems to be that for every bundle
a Maven ArtifactResolver is used to download that bundle and the file used during that process
is not reclaimed until the goal finishes executing. I see the following in ServiceMix:

[INFO] Apache ServiceMix :: Features :: Assemblies :: Apache ServiceMix (Full)  FAILURE [1:02.352s]
