Running karaf on z/os

Brad Taylor
I am attempting to run karaf on z/os.  I have successfully gotten it started, however I can not "talk" to it.  I utilize Putty as the telnet console.  After karaf starts up must characters I type come back with:
Error executing command: Invalid UTF-8 first byte: -109
I have karaf up on my windows box and when I issue:

karaf@root> ssh -l karaf -P karaf -p 8101 ca31
Connecting to host ca31 on port 8101
Error executing command: Session is closed

The corresponding log entries from karaf log are:
java.lang.IllegalStateException: Incorrect identification: line too long

I get similar results when I run the karaf client from my windows box.

Any hints appreciated.

Thank you
