8255227: java/net/httpclient/FlowAdapterPublisherTest.java intermittently failing with TestServer: start exception: java.io.IOException: Invalid preface

[dfuch]

Hi,

I stumbled on an issue in Stream.java where an assert was misplaced, preventing the proper IOException to be triggered. I believe this is what caused the FlowAdapterPublisherTest.java to fail with the "Invalid Preface" error on the server side.
In any case - I haven't observed this error again after tweaking the assert.

I have also updated the server side to print better diagnostic in case the Invalid Preface strikes again in the future...
