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
Prior to this commit, the tests we had in place for SpEL 'selector'
support did not assert what happens when a selector expression does not
match or when a selector header is not present.

When ReactorNetty2StompBrokerRelayIntegrationTests fail, typically there
are multiple exceptions "Connection refused: /127.0.0.1:61613" that
appear after we've conneted, sent CONNECT, and expecting CONNECTED, but
that does not come within the 10 second timeout.
61613 is the default port for STOMP. However, in all integration tests
we start ActiveMQ with port 0 which results in a random port. Moreover,
the stacktrace is for Netty 4 (not 5), and the eventloop thread id's
are different than the one where the connection to the correct, random
port was established.
The suspicion is that these are log messages from
MessageBrokerConfigurationTests which focuses on testing configuration
but nevertheless as a bean starts and attempts to connect to the default
port and fails. Perhaps those attempts to connect on the default port
somehow affect the ActiveMQ server, and it stops responding.
This change adds a no-op TcpClient in MessageBrokerConfigurationTests
to avoid unnecessary attempts to connect that are not needed.

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
This commit introduces DataBuffer::readableByteBuffers and
DataBuffer::writableByteBuffers, allowing restricted access to the
ByteBuffer used internally by DataBuffer implementations.
Closes gh-29943
This commit introduces new AOT processors that look for
`@RSocketExchange` annotated methods on interfaces implemented by beans
and registers reachability metadata accordingly:
* JDK proxies for the beans themselves
* invocation reflection for annotated methods
* binding reflection for arguments and return types
This allows to compile such clients to Native Images.
Closes gh-29877
