Get password from console via Java and JRuby

	# GIST: "pw_from_console.rb" under "https://gist.github.com/drhuffman12"
	# If you're dealing with a Java character array (such as password characters that you read from the console), you can convert it to a JRuby string with the following Ruby code:

	jconsole = Java::java.lang.System.console()
	password = jconsole.readPassword()
	ruby_string = ''
	password.to_a.each {\|c\| ruby_string << c.chr}

	# .. do something with 'password' variable ..
	puts "password_chars: #{password_chars.inspect}"
