Ciao Diego!
While working with cookies, we had some issues handling not valid
characters.
One of our legacy (non java) server was used to put a blank (' ') character
as value of a cookie.
But it seems that blank it's a forbidden char so tomcat was not able to
parse the cookie value.
Is it possible that in the scenario you described there's a any other cookie
containing
some not valid characters that prevent tomcat to handle all cookies
correctly?
If you have any doubt on that, you may try to access the cookie header
directly in order to see
which cookies the request contains.
