I find the idea that ATM systems might be programmed in C, C++, or Java quite terrifying. With C and C++, at least everyone knows they are skating on thin ice. But Java has been sold as 'secure' and 'easy to use'. In fact its concurrency support is sloppy, in ways that are highly likely to cause latent errors. The RTSJ 'real time' fixup engineering that has been done on it is a quixotic attempt to fit it for a completely inappropriate mode of use and does little or nothing to remedy its intrinsic defects. -- Bill-Findlay chez blue-yonder.co.uk ("-" => "")
