  ****************************************************************
  HOD received multiple SSH packets in a single TCP buffer
  during session connection for SSH. HOD failed to segregate
  the SSH header packet and data packets and a Java exception
  resulted, "NegativeArraySizeException" and failed to show
  the logon screen.
  

Problem conclusion

• The code was modified to handle the multiple SSH packets that
  appear in the TCP buffer during SSH negotiation.
  

Temporary fix
