We have problem installing odl-restconf feature in controller.

Step by step:
1. downloaded https://git.opendaylight.org/gerrit/dlux.git;
2. cd dlux
3. mvn clean install
4. ./distribution-dlux/target/assembly/bin/kataf
5. on controller console run "feature:install odl-restconf"

Error: Error executing command: Could not start bundle mvn:org.opendaylight.yangtools/concepts/0.7.0-SNAPSHOT in feature(s) odl-yangtools-common-0.7.0-SNAPSHOT: The bundle "org.opendaylight.yangtools.concepts_0.7.0.SNAPSHOT [79]" could not be resolved. Reason: Missing Constraint: Require-Capability: osgi.ee; filter="(&(osgi.ee=JavaSE)(version=1.7))"

We tried it on windows and linux too, on maven verision 3.3.1 and 3.2.5.

mvn --v
