karaf client fails in karaf-4.3.8 and 4.4.2

Sulfur-SR3 and Clorine-SR1 are respectively using karaf-4.3.8 and karaf-4.4.2

In these versions of karaf, when we try to launch the client (./karaf/target/assembly/bin/client), it fails with the following message:

Logging in as karaf
DefaultOpenFuture[ChannelShell[id=0, recipient=-1]-ClientSessionImpl[karaf@localhost/127.0.0.1:8101]]: Failed (IllegalArgumentException) to execute: Invalid UINT32 value: -1

This feature is used in transportpce tapi functional tests to install the odl-transportpce-tapi optional feature.

Since the tapi feature can no longer be installed, all tapi functional tests are failing on the gate (https://jenkins.opendaylight.org/releng/job/transportpce-tox-verify-sulfur/1372/consoleFull)

Karaf client is still failing with karaf-4.4.2, even if the exception is better managed:

Logging in as karaf
