Subject [jira] [Commented] (KARAF-3482) 100% cpu usage
Date Tue, 27 Jan 2015 20:08:35 GMT

    [ https://issues.apache.org/jira/browse/KARAF-3482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14294103#comment-14294103
] 

Jean-Baptiste Onofré commented on KARAF-3482:
---------------------------------------------

By the way (in the mean time that I create the tests platform), does the behavior the same
if you do:

{code}
karaf@root()> feature:repo-add cellar 3.0.1
karaf@root()> feature:install cellar
// wait that all Cellar bundles are in "active" state
karaf@root()> feature:install cellar-eventadmin
{code}

Thanks.
