This commit removes a list of hardcoded servers and version as this is
bound to get outdated and the reference guide/wiki is a more suitable
place for this.
This commit deprecates the various nullSafeHashCode methods taking array
types as they are superseded by Arrays.hashCode now. This means that
the now only remaining nullSafeHashCode method does not trigger a
warning only if the target type is not an array. At the same time, there
are multiple use of this method on several elements, handling the
accumulation of hash codes.
For that reason, this commit also introduces a nullSafeHash that takes
an array of elements. The only difference between Objects.hash is that
this method handles arrays.
The codebase has been reviewed to use any of those two methods when it
is possible.
Closes gh-29051
This commit disables support for evaluating SpEL expressions from
untrusted sources by default. Specifically, this applies to the
SpEL-based 'selector' header support in WebSocket messaging, which
includes the DefaultSubscriptionRegistry and the classes used to
configure the 'selector' header name (SimpleBrokerMessageHandler and
SimpleBrokerRegistration).
The selector header support remains in place but will have to be
explicitly enabled beginning with Spring Framework 6.1.
For example, a custom implementation of WebSocketMessageBrokerConfigurer
can override the configureMessageBroker() method and configure the
selector header name as follows.
registry.enableSimpleBroker().setSelectorHeaderName("selector");
Closes gh-30550
* use forEach and putIfAbsent to copy headers in DefaultClientRequestBuilder
* use forEach in ReactorClientHttpRequest and ReactorNetty2ClientHttpRequest
* circumvent ReadOnlyHttpHeaders.entrySet()
* ensure the fast path to LinkedCaseInsensitiveMap for forEach and putIfAbsent exists
Closes gh-29972
In some application setups, the WebSocket server does not transmit
the disconnect message to the client, so that the client has no idea
that the established connection has been terminated.
This issue arises when the application uses SimpleBrokerMessageHandler
and the error handler is set to the instance of
StompSubProtocolErrorHandler or an extended class that does not
override the handleErrorMessageToClient method.
The commit fixes disconnect message population so that
`java.lang.IllegalArgumentException: No StompHeaderAccessor` exception
is not thrown in the handleErrorMessageToClient method in
StompSubProtocolErrorHandler class.

This commit refactors some AssertJ assertions into more idiomatic and
readable ones. Using the dedicated assertion instead of a generic one
will produce more meaningful error messages.
For instance, consider collection size:
```
// expected: 5 but was: 2
assertThat(collection.size()).equals(5);
// Expected size: 5 but was: 2 in: [1, 2]
assertThat(collection).hasSize(5);
```
Closes gh-30104
The `echoWebSocketHandler()` method is not defined in the
`WebSocketConfigurer` interface and should therefore be annotated with
`@Bean` instead of `@Override`.
Closes gh-30183
