Update `SpringFactoriesLoader` so that the cache stores only the
factories and not the complete loader.
Prior to this commit, if a cache entry was added with the thread
context classloader, the loader instance would be added and the
classloader stored. If the thread context classloader subsequently
changes, and a call is made to `forDefaultResourceLocation` with
`null` for the classloader, the cached entry would be used which
contains the older classloader.

The compiler has a constants pool limit of 65536 entries per source file
which can be hit with a very large amount of beans to register in the
bean factory.
This commit makes sure to create separate source files if the number
of beans to register is very large. The main generated source file
delegate to those.
Closes gh-35044
This commit simplifies our dependency management for JUnit artifacts by
making use of the junit-jupiter and junit-platform-suite aggregator
artifacts.

After experimenting with our newly introduced core retry support
(RetryPolicy, RetryTemplate, etc.) and @Retryable support, it
became apparent that there are overlapping concerns between the current
RetryPolicy and BackOff contracts.
- RetryPolicy and BackOff both have stateful executions: RetryExecution
and BackOffExecution. However, only one stateful execution is
necessary.
- FixedBackOff and ExponentialBackOff already incorporate "retry" logic
in terms of max attempts, max elapsed time, etc. Thus, there is no
need to duplicate such behavior in a RetryPolicy and its
RetryExecution.
- RetryTemplate currently accepts both a RetryPolicy and a BackOff in
order to instrument the retry algorithm. However, users would
probably rather focus on configuring all "retry" logic via a single
mechanism.
In light of the above, this commit directly incorporates BackOff
in RetryPolicy as follows.
- Remove the RetryExecution interface and move its shouldRetry() method
to RetryPolicy, replacing the current RetryExecution start() method.
- Introduce a default getBackOff() method in the RetryPolicy interface.
- Introduce RetryPolicy.withDefaults() factory method.
- Completely overhaul the RetryPolicy.Builder to provide support for
configuring a BackOff strategy.
- Remove BackOff configuration from RetryTemplate.
- Revise the method signatures of callbacks in RetryListener.
The collective result of these changes can be witnessed in the
reworked implementation of AbstractRetryInterceptor.
RetryPolicy retryPolicy = RetryPolicy.builder()
.includes(spec.includes())
.excludes(spec.excludes())
.predicate(spec.predicate().forMethod(method))
.maxAttempts(spec.maxAttempts())
.delay(Duration.ofMillis(spec.delay()))
.maxDelay(Duration.ofMillis(spec.maxDelay()))
.jitter(Duration.ofMillis(spec.jitter()))
.multiplier(spec.multiplier())
.build();
RetryTemplate retryTemplate = new RetryTemplate(retryPolicy);

Prior to this commit, `WebMvcConfigurationSupport` would configure file
extensions/media types registrations based on classpath detection.
Since gh-33894, the detection of message converters is located in a
single place, `HttpMessageConverters`.
This commit updates the `WebMvcConfigurationSupport` to use the actual
message converters configured to decide which file extensions should be
set up for content negotiation.
See gh-33894
Prior to this commit, the classpath detection of various
`HttpMessageConverter` types was using an instance `ClassLoader`. The
main goal here was to provide the feature and being able to test it with
filtered classloaders.
It seems this approach fails with GraalVM and we need to ensure that
classpath detection is performed at class loading time for our GraalVM
feature (inlining such static booleans at build time).
As a result, we need to remove the tests for classpath detection.
See gh-33894
This commit uses the new `HttpMessageConverters` class for the HTTP
client (`RestTemplate` and `RestClient`) and HTTP server support.
This effectively removes the duplication of classpath detection for
message converters in multiple places: clients, server and the multipart
converter itself.
Instead of creating multiple instances of the same converters, this
allows applications to share converter instances as much as possible for
better memory efficiency.
As a result, this change also deprecates configuration methods in the
MVC support that are superseded by the new methods introduced for
`HttpMessageConverters` support.
Closes gh-33894
Prior to this commit, Spring Web would configure
`HttpMessageConverter<?>` collections on clients like `RestTemplate` and
on the server infrastructure, in `WebMvcConfigurationSupport`.
This commit introduces a high-level construct for building and
configuring ordered collections of converters.
This includes:
* configuration of well-known converters with classpath detection
* configuration of shared converters, or client/server specific
* configuration of custom converters
