Description

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.
