Fixed. That will be part of our next release (1.9.0) and available right
now using the SNAPSHOT/uploaded build from here:
http://download.java.net/maven/2/com/sun/grizzly/
Make sure you read the API documentation. In short, if you manipulate
the SocketChannel, you must make sure you either let Grizzly handle the
http headers, or handle it by yourself.

(uploading the new html now so refresh in a couple of min)
Let me know how it goes.
