[jira] [Created] (KARAF-6542) Refreshing sshd cause the ssh service to be unavailable

J. Brébec created KARAF-6542:
--------------------------------

             Summary: Refreshing sshd cause the ssh service to be unavailable
                 Key: KARAF-6542
                 URL: https://issues.apache.org/jira/browse/KARAF-6542
             Project: Karaf
          Issue Type: Bug
          Components: karaf
    Affects Versions: 4.2.6
            Reporter: J. Brébec


When a feature cause the bundle org.apache.sshd to be refreshed, then the ssh server is stopped and restarted. however, the restart doesn't work and the ssh service is then unavailable.

 

For example, installing bouncycastle into Karaf stop the ssh service. Restarting Karaf fixes this issue.

 

This issue come from a conflict between the thread context class loader (which can see the "old" sshd bundle) and a ServiceLoader pattern used in sshd. The ssh server failed to start with a ClassNotFound exception.
