Karaf version               4.4.2
  Java Virtual Machine        Java HotSpot(TM) 64-Bit Server VM version 
25.172-b11

bin/karaf works, but bin/client fails with the following error:
  DefaultOpenFuture[ChannelShell[id=0, 
recipient=-1]-ClientSessionImpl[karaf@localhost/127.0.0.1:8101]]: Failed 
(IllegalArgumentException) to execute: Invalid UINT32 value: -1

I have verified the ssh port is not in use prior to starting karaf using 
bin/start
sparrow:apache-karaf-4.4.2 paul$ netstat -an | grep 8101
sparrow:apache-karaf-4.4.2 paul$ 

What am I missing?
