This change removes the `MultiValueMap` nature of `HttpHeaders`, since
it inherits APIs that do not align well with underlying server
implementations. Notably, methods that allows to iterate over the whole
collection of headers are susceptible to artificially introduced
duplicates when multiple casings are used for a given header, depending
on the underlying implementation.
This change includes a dedicated key set implementation to support
iterator-based removal, and either keeps map method implementations that
are relevant or introduces header-focused methods that have a similar
responsibility (like `hasHeaderValues(String, List)` and
`containsHeaderValue(String, String)`).
In order to nudge users away from using an HttpHeaders as a Map, the
`asSingleValueMap` view is deprecated. In order to offer an escape
hatch to users that do make use of the `MultiValueMap` API, a similar
`asMultiValueMap` view is introduced but is immediately marked as
deprecated.
This change also adds map-like but header-focused assertions to
`HttpHeadersAssert`, since it cannot extend `AbstractMapAssert` anymore.

This commit updates the whole Spring Framework codebase to use JSpecify
annotations instead of Spring null-safety annotations with JSR 305
semantics.
JSpecify provides signficant enhancements such as properly defined
specifications, a canonical dependency with no split-package issue,
better tooling, better Kotlin integration and the capability to specify
generic type, array and varargs element null-safety. Generic type
null-safety is not defined by this commit yet and will be specified
later.
A key difference is that Spring null-safety annotations, following
JSR 305 semantics, apply to fields, parameters and return values,
while JSpecify annotations apply to type usages. That's why this
commit moves nullability annotations closer to the type for fields
and return values.

This commit upgrades our Mock Servlet classes for Servlet 6.1 support:
* the read/write `ByteBuffer` variants for `ServletInputStream` and
`ServletOutputStream` were not added as the default implementation
matches well the testing use case.
* Implement the session accessor with a simple lambda. Our mocks do not
simulate the scheduling of request/response processing on different
threads.
* Ensure that the response content length can only be written before the
response is committed. Calling those methods after commit is a no-op,
per specification.
Closes gh-33749
As of Servlet 6.1, the `ServletInputStream` and `ServletOutputStream`
offer read and write variants based on `ByteBuffer` instead of byte
arrays. This can improve performance and avoid memory copy for I/O
calls.
This was already partially supported for some servers like Tomcat
through specific adapters. This commit moves this support to the
standard `ServletHttpHandlerAdapter` and makes it available for all
Servlet 6.1+ containers.
Closes gh-33748
This commit updates the Spring Framework baseline for the Servlet, JSP
and WebSocket APIs.
This also removes the previously deprecated APIs in JSP `PageContext`
and guards against the deprecation of the `PushBuilder` API.
See gh-33918
This provides an implementation of an HTTP Handler Adapter that is coded
directly to the Eclipse Jetty core API, bypassing any servlet
implementation.
This includes a Jetty implementation of the spring `WebSocketClient`
interface, `JettyWebSocketClient`, using an explicit dependency to the
jetty-websocket-api.

This commit adds support for the "Partitioned" cookie attribute in
WebFlux servers and the related testing infrastructure.
Note, Undertow does not support this feature at the moment.
Closes gh-31454
Add helpers to CollectionUtils for building HashSets and LinkedHashSets
that can hold an expected number of elements without needing to
resize/rehash.
Closes gh-32291
This commit adds Javadoc to the `getContentLength` method of
`MockHttpServletResponse` to reflect that it gets its value from the
HTTP response header.
