Thank you so much for your suggestions!
 
The error is indeed in my code, specifically in a 
MultipartRequest-related class that I downloaded from JavaPro 
magazine.  I never suspected this code because I didn't write it.=
  I 
guess there is a bug in their code that I now have to investigate=
 
that;  at least I now know the source of the problem!
