A logical follow-up on commit 43d937, this change also removes (or
rather deprecates for now) writePrelude that is only of concern to
streaming SockJS session implementations.
Issue: SPR-12427
This change removes the need for the isStreaming field from the base
class AbstractHttpSockJsSession. This field was used to account for
differences between polling vs streaming SockJS sessions without having
to expose to sub-classes private fields that are otherwise protected
from concurrent access by the base class. The change manages to delegate
to sub-classes without providing direct access to protected fields.

This change designates Jetty SockJS integration tests to run as part of
the "performance", but not the main "publication", CI build due to
recurring low-level failures suspected to be Jetty issues, e.g.
"java.io.IOException: Cannot append to finished buffer" or
"java.io.IOException: Out of order Continuation frame encountered".
The tests will still run at once a day with the performance build but
should not fail the main build with false negatives. Also note that
an Undertow variant of the exact same tests, which hasn't been failing,
will continue to run as part of the main build.
The following two refinements have been added:
1) SockJS doesn't support binary messages so don't even try
2) don't bother if payload.length == 0

This commit introduces the SpringHandlerInstantiator
class, a Jackson HandlerInstantiator that allows to autowire
Jackson handlers (JsonSerializer, JsonDeserializer, KeyDeserializer,
TypeResolverBuilder and TypeIdResolver) if needed.
SpringHandlerInstantiator is automatically used with
@EnableWebMvc and <mvc:annotation-driven />.
Issue: SPR-10768
With this commit, Jackson builder is now used in spring-websocket
to create the ObjectMapper instance.
It is not possible to use the builder for spring-messaging
and spring-jms since these modules don't have a dependency on
spring-web, thus they now just customize the same features:
- MapperFeature#DEFAULT_VIEW_INCLUSION is disabled
- DeserializationFeature#FAIL_ON_UNKNOWN_PROPERTIES is disabled

Upgrade undertow dependency to 1.1.0.Final.
Add support for undertow 1.1.0.Final in the
UndertowRequestUpgradeStrategy, after a breaking change in the
`io.undertow.websockets.jsr.ConfiguredServerEndpoint` constructor.
Issue: SPR-12302
Prior to this change, duplicate SubProtocolHandlers could be registered
when configuring STOMP with several registrations:
public void registerStompEndpoints
(final StompEndpointRegistry registry) {
this.endpointRegistry.addEndpoint("/stompOverWebSocket");
this.endpointRegistry.addEndpoint("/stompOverSockJS").withSockJS();
}
This commit registers sub-protocols in a Set instead of a list (see
SubProtocolWebSocketHandler), thus fixing the issue.
Issue: SPR-12403
This commit introduces a new OriginHandshakeInterceptor. It filters
Origin header value against a list of allowed origins.
AbstractSockJsService as been modified to:
- Reject CORS requests with forbidden origins
- Disable transport types that does not support CORS when an origin
check is required
- Use the Origin request header value instead of "*" for
Access-Control-Allow-Origin response header value
(mandatory when Access-Control-Allow-Credentials=true)
- Return CORS header only if the request contains an Origin header
It is possible to configure easily this behavior thanks to JavaConfig API
WebSocketHandlerRegistration#addAllowedOrigins(String...) and
StompWebSocketEndpointRegistration#addAllowedOrigins(String...).
It is also possible to configure it using the websocket XML namespace.
Please notice that this commit does not change the default behavior:
cross origin requests are still enabled by default.

Before this change the simple broker simply removed subscriptions
upon receiving a DISCONNECT message assuming it was a result of
a client STOMP WebSocket session ending.
However, if the server-side application sends a DISCONNECT to
the broker in order to terminate a session, the STOMP WebSocket
session could remain unware without any further action. This
change ensures the simple broker sends a DISCONNECT_ACK message
downstream whenever it receives a DISCONNECT.
Issue: SPR-12288
This change adds a ChannelInterceptor that flips the immutable flag on
messages being sent. This allows components sending messages to leave
the message mutable for interceptors to further apply modifications
before the message is sent (and exposed to concurrency).
The interceptor is automatically added with the STOMP/WebSocket Java
and XML config and the StompSubProtocolHandler leaves parsed incoming
messages mutable so they can be further modified before being sent.
Issue: SPR-12321
The WebSocketMessageBroker config now allows wrapping the
SubProtocolWebSocketHandler to enable advanced use cases that may
require access to the underlying WebSocketSession.
Issue: SPR-12314
This change adds a new XhrTransport for the SockJs client
implementation. This transport is based on `UndertowClient`,
Undertow's HTTP client.
Note that this transport can be customized with an OptionMap that is
used by the Xnio worker backing the I/O communications (see
http://xnio.jboss.org).
Implementation tested with undertow 1.0.36, 1.1.0.RC3, 1.2.0.Beta1.
Issue: SPR-12008
This change adds a "Vary: Origin" HTTP response header for /info and
/iframe SockJS endpoints.
This is preventing proxies and browsers from caching a response and
reusing it for an invalid Origin.

Issue: SPR-12310
This change uses a ChannelInterceptor (inserted at index 0) to detect
when a DISCONNECT message is precluded from being sent on the
clientInboundChannel. This can happen if another interceptor allows
a runtime exception out from preSend or returns false.
It is crucial for such messages to be processed, so when detected
they're processed still.
