This happened only twice. I cannot reproduce the bug consistently. :(
But given that it has a very low start level (30), there's probably a timing
issue before any user bundles are started up.
The karaf configuration is untouched (i.e. the /etc folder is pristine).

Connecting using Linux ssh doesn't work, as well as Karaf client: (the server
isn't even running though, so it's not the client's fault)

Even though "BouncyCastle not registered" is shown, the client can connect
successfully if the SSH server is started up properly.
