Description

Accordingly documentation, if feature is available in multiple versions, the newest version have to be installed:

The <feature/> element contains the name of a feature. A specific feature version can be defined using the version attribute to the <feature/> element (<feature version="1.0.0">feature1</feature>). If the version attribute is not specified, Apache Karaf will install the latest version available.

Unfortunatelly it is not always the case.
Use case:
1) feature basit-thirdparty-jollyday references wrapped jar (jollyday library); this feature is available in two different versions (1.0.0-SNAPSHOT and 2.0.0-SNAPSHOT) and contains different versions of jolly (0.4.6 and 0.5.2 correspondingly);
2) bundle test-jolly uses packages from wrapped jar (jollyday library);
3) feature test-feature references basit-thirdparty-jollyday and test-jolly bundle.

Karaf repositories list contains both versions of basit-thirdparty-jollyday and test-feature:

karaf@root()> feature:list | grep basit
basit-thirdparty-jollyday     | 2.0.0.SNAPSHOT   |          | Uninstalled | ccp
                     |
basit-thirdparty-jollyday     | 1.0.0.SNAPSHOT   |          | Uninstalled | ccp
                     |
basit-test-feature            | 1.0.0.SNAPSHOT   |          | Uninstalled | ccp
                     |
karaf@root()>

If I try to install basit-thirdparty-jollyday feature - it works as expected: only 2.0.0.SNAPSHOT will be installed:

karaf@root()> feature:install -t -v basit-thirdparty-jollyday
Adding features: basit-thirdparty-jollyday/[2.0.0.SNAPSHOT,2.0.0.SNAPSHOT]
Changes to perform:
  Region: root
    Bundles to install:
      wrap:mvn:de.jollyday/jollyday/0.5.2

But if I try to install basit-test-feature, Karaf installs BOTH versions of basit-thirdparty-jollyday:

karaf@root()> feature:install -t -v basit-test-feature
Adding features: basit-test-feature/[1.0.0.SNAPSHOT,1.0.0.SNAPSHOT]
Changes to perform:
  Region: root
    Bundles to install:
      mvn:de.conrad.ccp.basit/test-jolly/1.0.0-SNAPSHOT
      wrap:mvn:de.jollyday/jollyday/0.4.6
      wrap:mvn:de.jollyday/jollyday/0.5.2
karaf@root()>

If I exclude bundle test-jolly from basit-test-feature, installation works as expected again (only new jolly feature will be installed)

The test projects to reproduce the problem and org.apache.karaf.features.cfg are attached
