Message5344

Likely the problem is response.session_id_name is a unicode object but 
Cookie expects a string. If that's the case it may or may not be 
Jython's fault. Jython has had some issues in the past where it returns 
unicode instead of strs, one common gotcha is Jython treats 
java.lang.Strings from Java as unicode objects. You'll need to narrow 
down where that unicode value came from originally.

The confusing error message is a bug, but that's a duplicate of #1305, 
so I'm closing this issue out. Please reopen this or open a new ticket 
if it turns out to be something on our side.
