i agree it's somewhat confusing but we can reduce this by sticking to 
the documentation and the behaviour of the implementation (sun's jdk 
that is).

where exactly does the 1.4 and the 1.4.1 differ?

another alternative is to stick to the distinction the javadocs makes 
wrt. to the following aspects:

* specific packages use specific, albeit sometimes, different 
encoding/charset names;
* some names are "canonical" others are "aliases,"
* some names are a MUST (Basic), others (the international version of 
the JDK) are a MAY (Extended).

this way, can be the test point 
for java.lang.* API encoding names, and something like (a new) test would emulate the 
same for the java.nio.* API encoding names.

if my comments above are acceptable, i can revise the getBytes classes 
to handle distinctly the last 2 points (canonical v/s alias, and basic 
v/s extended), and write a new test case for java.nio.* API 
conformance.  the pass/fail requirements can then be controlled with an 
'xfails' file.
