In both NetBeans 5.5.1 and 6.0 M10, java.io.Console is not supported.

However, the following program compiles and runs successfully from the command using
javac/java from both JDK 1.7.0b16 and JDK 1.6.0_02b5:

import java.io.Console;

public class AppConsole
{
    public static void main(final String[] args)
    {
        final Console console = System.console();

        final String input = console.readLine("Please your name: ");

        System.out.printf("Hallo [%s]\n", input);
    }
}

I get 
    Exception in thread "main" java.lang.NullPointerException
for the console.readLine(*) line.
