I'm not sure your handling of multi-valued Headers is correct

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Set Headers box like
Accept:application/json
X-User-Id:19640718
X-User-Role:Agent,Underwriter
X-Bob-Header:Bob,Robert,Kuhar
X-Bob-Header:Dread Pirate
X-Bob-Header:Manuel

2.  Send request to some server dumping the headers

What is the expected output?
Expected request to contain 3 separate instances of the X-Bob-Header;
  X-Bob-Header:Bob,Robert,Kuhar
  X-Bob-Header:Dread Pirate
  X-Bob-Header:Manuel

What do you see instead?
Actual request contains only a single X-Bob-Header;
  X-Bob-Header: Bob,Robert,Kuhar, Dread Pirate, Manuel

On what operating system, browser and browser version?
Chrome on OS X

When I curl the same request I get the behavior I expected on the server.  I'm 
not sure it is correct to pre-process the header values before you send them 
off.

$curl -v -i -X GET http://localhost:8080/headers -H 'Accept:application/json' 
-H 'X-User-Id:19640718' -H 'X-User-Role:Agent,Underwriter' -H 
'X-Bob-Header:Bob,Robert,Kuhar' -H 'X-Bob-Header:Dread Pirate' -H 
'X-Bob-Header:Manuel'

There is a github project at https://github.com/robertkuhar/gradle-quickstart 
which implements the server side of this as a java servlet.  Who knows, maybe 
the servlet API is wrong.
