From Claude:

> It's worth noting this is a common perception about Java, and there's some historical truth to it (especially with Swing desktop applications from the 2000s). However, the absolute statement "no Java app... ever" is the fallacy - it's an overgeneralization from limited personal experience to a universal claim.
