The above messages are gathered when my password contains the "=" character.

The log files for a password that doesn't contain the "=" character are:

Hi,

   +-From: "Kyritsi, Paraskeyh" <par...@si...> --

   |Hello all.  I am using JSCH to connect with an IP(username and
   |password) to a log console that i have created in my java
   |project.  When i choose a password that contains the "="
   |character, then i get the messages:
   ...
   |Why is that?  Is there any restriction in the jsch about the
   |passwords that a user should use, a restriction that doesn't
   |allow "=" as valid password character?

It is a first time to hear such a problem,
and I can not guess the reason for it at present time. 

Sincerely,
