WebSocket client API

[Pavel Rappo]

Hi,

I would appreciate if you help to review a WebSocket client API proposed for
JDK 9. This work is a part of JEP-110 [1] and has started its public path with
HTTP client review in March this year [2].

Proposed WebSocket API is relatively small and focuses on convenient exchange of
data in a fully asynchronous fashion. API consists of 6 types located in the
java.net package [3]:

1. WebSocket
2. WebSocket.Builder
3. WebSocket.Incoming
4. WebSocket.Incoming.Chunks
5. WebSocket.Outgoing
6. WebSocketException

Starting point is a class description for java.net.WebSocket. Along with
in-javadoc examples, several API test samples are provided in the webrev [4] and
named test/java/net/WebSocket/Example%.java. They are only for informational
purposes and won't be included in the final version of the API.

I would appreciate any feedback on this API. Thanks.
