RFR [10] - 8181176: java/net/httpclient/websocket/ConnectionHandover.java times out

[Chris Hegarty]

This is a request for review of a minor test bug that causes the
aforementioned test to fail intermittently. The issue is that the
mock test server expects to read the complete HTTP request with
a single read call. It should, however, be prepared to perform
more than one read call.
