tests impossible to pass with class library written using only spec?

[Noa Resare]

I looking around in some java.io mauve failures i found some failing
test code in gnu/testlet/java/io/OutputStreamWriter/jdk11.java reading 

	// Note that for java.io the canonical name as returned by
        // getEncoding() must be the "historical" name. ISO8859_1.
        harness.check(osw2.getEncoding(), "ISO8859_1", 
		"OutputStreamWriter(writer, encoding)");
        osw2.close ();
        osw2 = new OutputStreamWriter(baos2, "latin1");
        harness.check(osw2.getEncoding(), "ISO8859_1", 
		"OutputStreamWriter(writer, encoding) // alias");
        osw2.close ();

Ah, simple I thought. It must be a list in the java class library
specification that tells what the historical names are. Now i know there
is no such list. That leads me to a more general question: is it ok for
mauve to test functionality that there is no way to implement using only
the class library spec (or looking at the code of the of the tests
preformed and just returning what is asked for)?

The Java Class libries Second Edition Volume 1 lists them under the
String constructor description. An online copy can be found at:
http://java.sun.com/j2se/1.4.2/docs/guide/intl/encoding.doc.html
in the column "Canonical Name for java.io and java.lang API"

Cheers,

Mark
