Prior to this commit, Spring MVC and WebFlux would consider the
"kotlinx.serialization" JSON codecs and converters in addition to other
JSON alternatives like Jackson, Gson and Jsonb.
This would cause issues because while in most cases this library is only
involved if the type is annotated with "@Serializable", this is not true
for Java enums. In this particular case, the codec shadows Jackson and
causes issues.
This commit now considers kotlinx.serialization JSON support as an
alternative to Jackson. Just like Jsonb and GSON, this is only
auto-detected if Jackson is not present.
We received consistent feedback that kotlinx.serialization is popular in
Kotlin libraries and is often a transitive dependency. As a result, we
cannot consider its presence on the classpath as a strong enough signal
to configure it by default.

Prior to this commit, several common HTTP headers were ignored from the
data binding process when collecting property values, in gh-34039 and
gh-34182.
This commit completes the initial enhancement by ensuring that the
default header predicate is also considering cases where constructor
binding is applied and the Java type has a lowercase variant of the HTTP
header name to filter.
Fixes gh-34292
This test was already ignored as of Java 21 because of a Java behavior
change, and now it started failing as of 17.0.14.
This commit removes the test entirely.
This commit refines KotlinDetector usages and implementation in order
to remove preliminary KotlinDetector#isKotlinReflectPresent invocations
and to ensure that KotlinDetector methods are implemented safely and
efficiently for such use case.
Closes gh-34275
This commit ensures that checks for PathResource locations are skipped
because this resource implementation will always resolve under the
current location.
Closes gh-34167
Prior to this commit, HTTP request data binding had been improved to
filter out by default the "Priority" header in #34039.
This commit extends the set of filtered header names with:
"Accept", "Authorization", "Connection", "Cookie", "From", "Host",
"Origin", "Priority", "Range", "Referer", "Upgrade".
If an application wishes to let those header be bound, it will need to
configure the binder and replace the default header predicate by calling
`setHeaderPredicate`.

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.
Closes gh-33913
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.

Make it public and move it down to the annotations package alongside
InitBinderBindingContext. This is mirrors the hierarchy in Spring MVC
with the ExtendedServletRequestDataBinder. The change will allow
customization of the header names to include/exclude in data binding.
See gh-34039
Before this commit, in Spring Framework 6.2, Kotlin value class
unboxing was done at CoroutinesUtils level, which is a good fit
for InvocableHandlerMethod use case, but not for other ones like
AopUtils.
This commit moves such unboxing to InvocableHandlerMethod in
order to keep the HTTP response body support while fixing other
regressions.
Closes gh-33943
After our Tomcat 11 upgrade, several WebFlux integration tests with
Tomcat started failing because Tomcat considers some chunked client
requests as invalid.
While we're investigating this, this commit temporarily disables the
relevant tests.
