             Summary: Unable to connect to the console
                 Key: KARAF-4792
                 URL: https://issues.apache.org/jira/browse/KARAF-4792
             Project: Karaf
          Issue Type: Bug
    Affects Versions: 4.0.7, 4.0.6
         Environment: Mac/Linux
            Reporter: Carl-Philipp Harmant


Migrating from Karaf 3.0.4 to 4.0.x, and after deploying our app, impossible to 
connect to the console in local or via ssh. I activated logs into 
org.apache.karaf.shell.cfg to be able to see that:

Any clue of what's going on ?
