This commit deprecates all methods in org.springframework.scheduling
that use
- Date, in favor of variants that take an Instant.
- long & TimeUnit, in favor of variants that take a Duration.

This commit adds the supporting testing infrastructure using the
`RuntimeHintsAgent`. Given that the agent is loaded by the JVM running
the test suite, we can then use it to record method invocations at
runtime and check whether the prepared `RuntimeHints` match the expected
behavior.
This commit contributes the `RuntimeHintsRecorder`. With this, we can
record relevant method invocations for a given lambda, focusing on a
specific part of the code behavior. This returns a
`RuntimeHintsInvocations` instance, which is an AssertJ assert provider.
From there, we can perform assertions on the recorded invocations and
check that a given collection of hints cover the reflection, resources
and proxies needs at runtime.
This also ships the `@EnabledIfRuntimeHintsAgent` opinionated
annotation: this applies the `RuntimeHintsAgentCondition` JUnit
extension that detects whether the `RuntimeHintsAgent` is loaded by the
current JVM. Tests annotated with this will be skipped if the agent is
not present. This annotation is also tagged with a JUnit `@Tag` to
gather such tests in a specific `"RuntimeHintsTests"` test suite.
In the Spring Framework build, we have chosen to isolate such tests and
not load the agent for the main test suite ("RuntimeHintsTests" tests
are excluded from the main suite). While the agent's intent is to be as
transparent as possible, there are security and access considerations
that could interefere with other tests.
With this approach, we can then create a separate test suite and run
agent tests in a dedicated JVM.
Note that projects using this infrastructure can choose to use the
condition by itself in a custom annotation.
Here is an example of this testing infrastructure:
```
@EnabledIfRuntimeHintsAgent
class MyTestCases {
@Test
void hintsForMethodsReflectionShouldMatch() {
RuntimeHints hints = new RuntimeHints();
hints.reflection().registerType(String.class,
hint -> hint.withMembers(MemberCategory.INTROSPECT_PUBLIC_METHODS));
RuntimeHintsInvocations invocations = RuntimeHintsRecorder.record(() -> {
Method[] methods = String.class.getMethods();
});
assertThat(invocations).match(hints);
}
}
```

Ideally one would pass WebClient directly to HttpServiceProxyFactory,
but two need to remain decoupled. This commit adds static, shortcut
methods to WebClientAdapter to create an HttpServiceProxyFactory, thus
eliminating the step to wrap the WebClient.
Update the `TestCompiler` so that classes can be defined using
a `Lookup`. This update allows package-private classes to be
accessed without needing a quite so unusual classloader setup.
The `@CompileWithTargetClassAccess` should be added to any
test that needs to use `Lookup` based defines. The test will
run with a completed forked classloader so not to pollute the
main classloader.
This commit also adds some useful additional APIs.

With a Java 8 baseline in place for quite some time now, it no longer
makes sense to refer to features such as annotations as "Java 5
annotations".
This commit also removes old `Tiger*Tests` classes, thereby avoiding
duplicate execution of various tests.
This commit improves the documentation for test execution events,
especially with regard to the fact that, by default, a
BeforeTestClassEvent is not published for the first test class using a
particular ApplicationContext.
This commit also introduces tests that verify the default behavior and
the ability to change the default behavior with a custom
TestExecutionListener that eagerly loads the context.
