 It already does have this -- see gnu/gcj/convert/IOConverter.java.
 In fact this precise alias is already there.
 In theory "ISO-8859-1" should be mapped to lower case and then looked up
 in the hash table.
 Why doesn't this work for you?

 Ok - I've figured this out.  I'm running apache Tomcat, which uses the Xerces
 XML parser.  The XML documents say they're in "ISO-8859-1".  Xerces then
 converts this MIME name into something it thinks is supported by Java - in
 this case "ISO8859_1".  We don't understand ISO8859_1, and throw an
 UnsupportedEncodingException.  Xerces catches this, and rethrows it with the
 original name (ISO-8859-1).  I was seeing the results of the second throw :-)
 
 So, we just need to ad ISO8859_1 to IOConverter.java.  I'll submit a patch.

 Hrm... I'll look into this...  frustrating....
 
 Thanks for the pointer,

The runtime needs to have the notion of character encoding aliases... like ISO-8859-1 == 8859_1.

tomcat reads many xml files with assert an "ISO-8859-1" encoding, and the only work-around now is to hack this alias into libgcj.
