Access-Control-Allow-Credentials CORS header, used to
allow cookies with CORS requests, is not set to true
anymore by default when enabling CORS with
@CrossOrigin or global CORS configuration in order to
provide a more secured default CORS configuration.
The related allowCredentials property now requires to
be set to true explicitly in order to support cookies
with CORS requests.
Issue: SPR-16130
MockMvc now properly detects the presence of an AsyncContext and
re-uses the response instance used to start it.
This commit also includes a minor fix in
ResponseBodyEmitterReturnValueHandler to ensure it does not disable
ETag related content buffering for reactive return values that do not
result in streaming (e.g. single value or collections).
Issue: SPR-16067
Prior to this commit, the Resource `HandlerMapping` configured by
`@EnableSpringMvc` would be set up with only one custom
`HandlerInterceptor` (the one exposing the `ResourceUrlProvider` for
resolving URLs of static resources).
This behavior is not consistent with the rest of the default
configuration which leverages the interceptors configured against the
interceptor registry (with possible user-provided ones).
This change allows to register interceptors against resource handling;
this can be useful for metrics purposes, as in
spring-projects/spring-boot#10335.

The Javadoc on tag classes now has all the information including a
list of all tags at the package level, HTML tables listing tag
attributes in each tag class, and class level description that is
as good or in many cases better than what was in the reference.

Includes unified detection of Kotlin's optional parameters in MethodParameter.isOptional(), reduces BeanUtils.findPrimaryConstructor to Kotlin semantics (for reuse in AutowiredAnnotationBeanPostProcessor), and finally introduces a common KotlinDetector delegate with an isKotlinType(Class) check.

Issue: SPR-16020
This commit introduces the following changes.
1) It adds a new Spring @NonNull annotation which allows to apply
@NonNullApi semantic on a specific element, like @Nullable does.
Combined with @Nullable, it allows partial null-safety support when
package granularity is too broad.
2) @Nullable and @NonNull can apply to ElementType.TYPE_USE in order
to be used on generic type arguments (SPR-15942).
3) Annotations does not apply to ElementType.TYPE_PARAMETER anymore
since it is not supported yet (applicability for such use case is
controversial and need to be discussed).
4) @NonNullApi does not apply to ElementType.FIELD anymore since in a
lot of use cases (private, protected) it is not part for the public API
+ its usage should remain opt-in. A dedicated @NonNullFields annotation
has been added in order to set fields default to non-nullable.
5) Updated Javadoc and reference documentation.
Issue: SPR-15756
Prior to this commit, HTTP Range requests were only supported by the
ResourceHttpRequestHandler when serving static resources.
This commit improves the `HttpEntityMethodProcessor` and
the `RequestResponseBodyMethodProcessor`. They now extract
`ResourceRegion`s from the `Resource` instance returned by the
Controller and let the Resource-related message converters
handle the writing of the resource (including partial writes).
Controller methods can now handle Range requests for
return types that extend Resource or HttpEntity:
@RequestMapping("/example/video.mp4")
public Resource handler() { }
@RequestMapping("/example/video.mp4")
public HttpEntity<Resource> handler() { }

Includes general streamlining of dependency declarations with reduced version variables, direct use of EclipseLink 2.7 and its implicit JPA 2.2 dependency in spring-orm, mixed use of Hibernate 5.2.10 and 5.1.10 for integration tests, as well as an upgrade to Jetty 9.4.7 RC0 and a downgrade to Groovy 2.4.12 (since Groovy 2.5 won't be final in time for Spring Framework 5.0).
