Good catch!
This is just wrong! It is not a perspective thing. A container will
NEVER call onDataAvailable after the first invocation unless isReady has
been called AND it returned false.

The container will subsequently invoke the onDataAvaialble method when data
becomes available to read, if and only if isReady method on
ServletOutputStream, described below has been called and returned false.
Ditto for write listener.
