I do not think that this is a JServ bug.
I'm not a servlet ace, but if you read the API spec for BufferedReader.read() it says
that it blocks until a character is ready to be read. I'd guess that there is no
input available for your stream to read so it is patiently following the spec and
blocking until one becomes available. Use in.ready() to determine if read() will
block or not.
e.g.,
if ( in.ready() )
out.println( "input is: " + in.read() );
else
out.println( "nothing to read" );
But unless you have something that sends "binary data in the body of the request"
(quoted from the ServletRequest.getInputReader() method description) I'm not sure it
makes sense to use this particular construct. I think this would require you to at
least use a doPost and send your form data via a POST, but now I'm really beyond what
I know. Get parameters are better fetched with methods like getParameter etc.
just a thought.

P.S. All of this I obtained by reading the Java I/O API and doing a few quick tests.
Need to understand how the calls/objects you are making work before just jumping in
and using them (but hey, we all get excited and jump in from time to time :-).
