[Bug libgcj/21606] New: java.net.URI fails to decode lowercase hex codes

["brion at pobox dot com" <gcc-bugzilla@gcc.gnu.org>]

URIs may contain special hexadecimal byte codes in the format %HH where H is a
hexadecimal digit, either upper or lowercase. (RFC 2396 2.4.1)

When given a string containing lowercase hex codes such as %2c, the URI
constructor throws a URISyntaxException.

Steps to reproduce:
1. new URI("/a%2cb")

Actual results:
A URISyntaxException is thrown.

Expected results:
A happy, usable URI object. This works as expected on Sun's JDK 1.5.0.

Additional information:
GCC 4.0 compiled from source release on an Ubuntu Linux 5.04 "Hoary" system.
