ssh problems lead to netconf connector problems and bin/client failures

https://jenkins.opendaylight.org/bgpcep/job/bgpcep-csit-1node-userfeatures-only-boron/

the problems i ma hitting are the following ones:
1) bin/client is not able to connect to karaf
[odl@tobereplaced distribution-karaf-0.5.0-SNAPSHOT]$ ./bin/client -u karaf
client: JAVA_HOME not set; results may vary
Logging in as karaf

[odl@tobereplaced distribution-karaf-0.5.0-SNAPSHOT]$

i use
java -version
openjdk version "1.8.0_51"
OpenJDK Runtime Environment (build 1.8.0_51-b16) OpenJDK 64-Bit Server VM (build 25.51-b03, mixed mode)

2) i am unable to configure e.g. bgp peer via netconf connector, because i receive 404 every time i want to use it.

I believe this 2 things are related together.
POssibly https://bugs.opendaylight.org/show_bug.cgi?id=5917 is something similar.
