[ https://svn.apache.org/r1723660 ]
SOLR-8453: Fix raw socket test to correctly use HTTP spec: headers in HTTP are
US-ASCII, body's Content-Length is number of bytes (not chars!), PrintWriter
swallows Exceptions and was not needed (Forbidden apis found the bug, but fix
was incorrect)
> Jetty update from 9.2 to 9.3 causes the server to reset formerly legitimate
> client connections.

> The basic problem is that when we are streaming in updates via a client, an
> update can fail in a way that further updates in the request will not be
> processed, but not in a way that causes the client to stop and finish up the
> request before the server does something else with that connection.
> This seems to mean that even after the server stops processing the request,
> the concurrent update client is still in the process of sending the request.
> It seems previously, Jetty would not go after the connection very quickly
> after the server processing thread was stopped via exception, and the client
> (usually?) had time to clean up properly. But after the Jetty upgrade from
> 9.2 to 9.3, Jetty closes the connection on the server sooner than previous
> versions (?), and the client does not end up getting notified of the original
> exception at all and instead hits a connection reset exception. The result
> was random fails due to connection reset throughout our tests and one
> particular test failing consistently. Even before this update, it does not
> seem like we are acting in a safe or 'behaved' manner, but our version of
> Jetty was relaxed enough (or a bug was fixed?) for our tests to work out.
