Description of problem:
This is a regression most likely caused by fix to bug #1299870

The problem is that when trying to clone repository via kie-config-cli.sh
I'm getting an exception " Auth fail" when trying to authenticate / clone repository from ssh based url
full stacktrace at the bottom

Version-Release number of selected component (if applicable):
BPM Suite 6.2.2 patch

How reproducible:
Always

Steps to Reproduce:
1. deploy BPM Suite for EAP
2. unpack bxms.supplementary.tools.latest.zip and navigate to jboss-brms-bpmsuite-6.2-supplementary-tools/kie-config-cli-dist

3. run kie-config-cli.sh, accept default repo url and try to authenticate your user (one of the users declared in EAP for business central)

Actual results:
Exception in (see below) displayed - impossible to "login" to kie-config-cli.sh

Expected results:
It should be possible to authenticate the user.
