[Bug classpath/22850] java.nio.charset.Charset: case-sensitive, aliases missing |

I consider case-sensitivity a bug, dunno about
missing aliases. As they are for convinience, the
more the better?

for (int i = 0; i < list.length; i++) {
String cs = list[i];
System.out.println(cs + " = " + Charset.isSupported(cs));
}

The mauve test for this is/will be
gnu.testlet.java.nio.charset.Charset.forName2
It checks the availability of of certain charsets using case-insensitive names.
A couple of them will fail on JDK <= 1.5.
public void test(TestHarness h) {
/*
* Check for standard encodings using case-insensitive and
alternative
* names.
*/
// IANA name for UTF-8
checkCharset(h, "uTf-8");
// UTF-8 names from
//
http://java.sun.com/j2se/1.5.0/docs/guide/intl/encoding.doc.html
checkCharset(h, "utf8");
checkCharset(h, "UtF-16bE");
checkCharset(h, "uTf-16Le");
// IANA names for 8859_1
checkCharset(h, "IsO-iR-100");
checkCharset(h, "iSo_8859-1");
checkCharset(h, "LATIN1");
checkCharset(h, "L1");
checkCharset(h, "IbM819");
checkCharset(h, "cp819");
checkCharset(h, "CSisolATIN1");
// IANA names for US-ASCII
checkCharset(h, "iSo-Ir-6");
checkCharset(h, "AnSi_X3.4-1986");
checkCharset(h, "IsO_646.IRV:1991");
checkCharset(h, "AsCiI");
checkCharset(h, "IsO646-us");
checkCharset(h, "Us");
checkCharset(h, "IbM367");
checkCharset(h, "cP367");
checkCharset(h, "CSASCII");
// UTF-8 names from
// http://oss.software.ibm.com/cgi-bin/icu/convexp?s=ALL
/* These fail on official implementation of <= 1.5 */
checkCharset(h, "ibm-1208");
checkCharset(h, "ibm-1209");
checkCharset(h, "ibm-5304");
checkCharset(h, "ibm-5305");
checkCharset(h, "windows-65001");
checkCharset(h, "cp1208");
}

Forgot to mark this as fixed.
