Hugo Arès commented on SSHD-738:
--------------------------------
I totally agree that they should not use such an old version. I will send the
message to all our users to upgrade but it's very unlikely they will all do it.

Can you handle this specific case of underflow and print this as info (or
debug) instead?
> "BufferException: Underflow" warning is frequently reported
