This PR fixes a regression introduced in [JDK-7026262](https://bugs.openjdk.org/browse/JDK-7026262); we started closing the exchange instead of the output stream, and exchange closes the connection when wrapped stream is not set. As an unintended side effect, the server started closing connections after handling a HEAD request.
The proposed change is to set the wrapped stream to a zero-length FixedLengthOutputStream before closing the exchange. This allows the connection to be reused.
The attached test verifies if 2 consecutive HEAD requests use the same connection. It succeeds with the proposed change, fails without it. All other tier1-3 tests continue to pass.
