Prior to this commit, if AOT processing of a test's ApplicationContext
failed, the TestContext Framework (TCF) still attempted to load the
context via standard (JVM) mechanisms when running in AOT mode.
For example, if a test class uses Spring Boot's @MockBean, AOT
processing of that test's context will fail with a WARN log message,
and there will no mapping from that test class to an AOT-generated
ApplicationContextInitializer (ACI). Consequently, when the test suite
is run in AOT mode that particular test class will currently fail with
a confusing stack trace due to the fact that Spring Boot's
SpringApplication attempts to locate a "main" ACI instead of the
missing "test" ACI (missing because it was not generated during AOT
processing).
In general, the TCF should not attempt to load an ApplicationContext in
"JVM mode" while running in "AOT mode".
This commit therefore reworks the logic in
DefaultCacheAwareContextLoaderDelegate to fail fast (with a meaningful
error message) if an AOT-generated ACI cannot be found while running in
AOT mode. This avoids the aforementioned confusion when @MockBean tests
fail in AOT mode (on the JVM or within a native image), and it also
helps to diagnose build problems if AOT processing has not yet been
performed for the project's test suite.

Reflective getHeaders calls to be revisited; see GitHub issue #8938 in Jetty project.
HttpOutput optimization commented out still in order to avoid alpha build dependency.
See gh-29575
For a transition period, LocalVariableTableParameterNameDiscoverer logs a warning for each successful resolution attempt now, suggesting that -parameters was missed.
See gh-29531
See gh-29559
LocalVariableTableParameterNameDiscoverer is not registered by default anymore now.
Java sources should be compiled with `-parameters` instead (available since Java 8).
Also retaining standard Java parameter names for all of Spring's Kotlin sources now.
Closes gh-29531
- The return values of ServletWebRequest.validateIfUnmodifiedSince and
DefaultServerWebExchange.validateIfUnmodifiedSince are not used. So I
think that it is better to remove the return statements.
- Add missing @Nullable declarations to eTag method parameters.
- Simplify if statements
Closes gh-29460
As a follow-up to gh-29277, and since the JAXB support is now
triggered by the classpath presence of a JAXB implementation,
it makes sense to make SourceHttpMessageConverter, previously
configured unconditionally, optional.
That makes a big difference on native (1M of RSS reduction
with current typical Spring Boot 3 arrangement, 3.4M when
other usages of XML are not reachable).
It also brings more consistency between Spring MVC
and Spring WebFlux, and means that XML support for
Spring web applications now needs to be enabled explicitly.
As a consequence, Spring web applications using
javax.xml.transform.Source now needs to configure
SourceHttpMessageConverter explicitly in RestTemplate or
Spring MVC.
