I very much assume this wants to call java.io.Reader.ready
I very much assume this wants to call java.io.Reader.ready

...seeing that there is no java.io.Reader.available.  (And then, there's no good
way to map from java.io.Reader.ready's boolean value to
css.io.XInputStream.available's long value, so conservatively map true to 1.)

But I have no idea how to trigger this code.
