BEGIN event since there is data available.
I figure this is a bug?
The API is designed mostly for biderectional transfer. If somehow you
don't want to do that, then there's a lot less value in it (a thread
isn't that expensive, if all you want is wait a little bit before
generating a response).
If there's data available in the begin event (if the requests you use
send a request body), you should read it and if this "bug" is fixed,
it won't make a difference for you.

I'm sorry but I don't understand your answer.
First of all, I use bidirectional communication: the client says A and
the server says B, the client says C, etc.. However, since the server
does not get a READ event for the initial A, the server just sits there
and does not respond at all. It needs a READ event to be able to read
from the input stream.
Secondly, I'm trying to understand the API. Either it IS or it IS NOT
allowed to read from the input stream in the BEGIN event. If I rely on a
certain behavior while reading in the BEGIN event now, it might very
well break in the future because I might be relying on the side effect
of an implementation detail. The answer seems to be to me a simple yes
or no; the documentation implies no.
Finally, I expect to get a READ event if there is data available, or so
the API seems to suggest. Then it seems to me that it is a bug if I
don't. To be helpful I am reporting it, so that if it is indeed a bug,
it may be fixed and the entire Tomcat community can profit from the bug
fix. Even a simple acknowledgement that it is a bug without a fix is
fine too, then I will look into the source myself and see if I can
locate the problem and suggest a patch/fix.
