I was wondering the same thing. My understanding of the definition of "console" 
is a bidirectional byte channel with a keyboard & screen on the other end. It 
has no concept of stdout vs. stderr. It just has a display (or in the old days, 
a printer).

The function of a "shell" is to intermediate between one or more executing 
programs and the console. It figures out how & when to actually display on the 
console any stuff written to stdout and/or stderr by one of the programs it has 
launched.

A program can also access its console (if any) directly by opening /dev/tty or 
whatever, thereby bypassing the shell.

So I would think writing to something called "System.console()" from Java 
(which is a program) would have nothing to do with Java's stderr or stdout, 
except for a possible downstream interleaving with what the shell may also be 
writing to the console at the same time.
