Defaul.java
System.out.println(Charset.defaultCharset());

The output for "nonexist" (not supported) LC_ALL is (at least on 
Solaris): US-ASCII

The output is the same as set LC_ALL from commandline:

$ export LC_ALL=nonexist
bash: warning: setlocale: LC_ALL: cannot change locale (nonexist)

$ echo $LC_ALL
nonexist

$ jdk/bin/java Default
US-ASCII

I'm not sure why though. Also not sure whether it's the same across 
platforms, settings. So I make it run with the "nonexist" locale to get 
the String UNSUPPORTED.

Thanks,
