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");

Includes hashCode optimization in AbstractBeanFactoryBasedTargetSource.
Includes ThreadLocal naming fix in ThreadLocalTargetSource.

Closes gh-30581
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.

This commit ensures that ClientHttpRequest implementations implement
StreamingHttpOutputMessage, so that they do not expose an OutputStream,
but store a handle capable of writing to a stream instead.
Closes gh-30557
gh-23846 introduced a new
MethodArgumentNotValidException(Executable, BindingResult)
constructor that can be advantageously replaced by using
MethodArgumentNotValidException(MethodParameter, BindingResult)
in ModelAttributeMethodProcessor.
This commit updates ModelAttributeMethodProcessor accordingly,
and deprecates MethodArgumentNotValidException(Executable,
BindingResult) in favor of
MethodArgumentNotValidException(MethodParameter, BindingResult).
Closes gh-30558
This commit removes the build configuration for the repository
"libs-spring-framework-build", as it is not needed anymore for the
dependencies it contains.
