Maybe ssh was not initialized properly? Although I do not see anything wrong in netconf-testtool log [].

This seems to be duplicate of YANGTOOLS-805.

What happened in above mentioned issues is that ODL cannot properly mount either testtool or CSS server. Because of the YANGTOOLS-805, some schemas from mountpoint are not properly parsed and hence, are not part of the mountpoint's schema context.

Therefore you can see errors like "java.lang.IllegalArgumentException: Could not find module for namespace urn:opendaylight:params:xml:ns:yang:controller:netty:eventexecutor" because ODL cannot properly parse responses from mounted device due to its incomplete mountpoint's schema context.
