Environment: Windows XP, JBOSS AS 4.2.1.GA

New maemo Mozilla browser has a "feature" which sends duplicate charset
parameter in the POST Content-type header. This causes following exception:
java.io.UnsupportedEncodingException: UTF-8;charset=UTF-8

The erraneous* Content-Type header causing this is
"Content-Type: application/x-www-form-urlencoded; charset=UTF-8;charset=UTF-8"
("User-agent: Mozilla/5.0 (X11; U; Linux armv6l; en-GB; rv:1.9a6pre) Gecko/20070810
Firefox/3.0a1 Tablet browser 0.1.16 RX-34_2007SE_4.2007.38-2")
Windows version of Mozilla causes no problems:
"Content-Type: application/x-www-form-urlencoded; charset=UTF-8"
(User-agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; fi; rv:1.8.1.7) Gecko/20070914
Firefox/2.0.0"
* I don't think RFC2616 strictly speakings prohibits duplicate attributes.
This seems to be Catalina issue, but I don't know which version JBOSS AS 4.2.1.GA is
using, so I'm submitting this here.
