Base64 and BasicAuthentication patch
I've found a potential bug in the Basic Authentication module. I have users
and some user's username is contains national characters (encoded in UTF-8).
The HTTP header based authentication is fails when the username or the
password contains multibyte characters.
The root of the bug is the Base64 decoder, which decodes the Base64 stream to
char array: converts each byte to individual char, this decode method corrupts
the multibyte characters...
The patch converts the Base64 input to byte array instead char array, and
converts this byte array to String - with the encoding which specified in the
JVM. The patch is not beautiful :), and I've tested it only in a JBoss 5.1.0.GA
application server (it uses catalina).
