>
> Currently, each ChunkedResponse object creates a PrintWriter that allocates
> 8K for its StreamEncoder. There is a channel close listener that is
> registered in ChunkedNettyOutputStream that prevents the ChunkedResponse from
> being garbage collected until the request connection is closed. However, if
> the connection keepAlive is set, the connection will not be closed until the
> client decides to close it and therefore the ChunkedResponse can't be garbage
> collected until then. We need to revisit registering the close listeners and
> ensure all request based resources can be released as soon as the response is
> closed.
