I'm seeing constant 100% cpu usage after installing cellar.
Steps to reproduce:

1. Download Karaf 3.0.2
2. Run bin/karaf
3. Run feature:repo-add mvn:org.apache.karaf.cellar/apache-karaf-cellar/3.0.1/xml/features
4. Run feature:install cellar cellar-eventadmin

After this, cpu usage goes near 100% and won't drop.
After setting DEBUG log I see tons of:
