Sigh... of course :-(

<sound of slapping forehead>

I guess I'm right in thinking that the JAI folk never got round to
disk-based tile caching ?

I see in this discussion it's suggested to handle this by sub-classing
TiledImage...

...and this sounds easier than implementing a custom TileCache class.
What approach have you used in your own work ?
