Prior to this commit, a DataSize input string could not be parsed if it
contained any whitespace.
With this commit, a DataSize input string can contain leading, trailing,
or 'in between' whitespace. For example, the following will be parsed
to the same DataSize value.
- "1024B"
- "1024 B"
- " 1024B "
- " 1024 B "

The previous change to the tests resulted in a failure on Windows when
using the DefaultResourceLoader by expecting an exception when no
exception is thrown.
This commit narrows the scope of the if-clause to expect an exception
only when using the FileSystemResourceLoader on Windows.
See gh-28703, gh-28746
The tests introduced in commit 9868c28c73 pass on Mac OS and Linux but
fail on Microsoft Windows.
This commit updates the tests so that they pass on MS Windows as well.

This commit fixes a NullPointerException issue in the constructor hint
predicate. Prior to this commit, a hint for a constructor was directly
looked up and dereferenced a type hint without checking if there was one
first.
This commit adds new tests for the `ApplicationContextAotGenerator`,
this time leveraging the `RuntimeHintsAgent` that checks the need for
runtime hints at runtime.
See gh-27981
In order to write proper integration tests for the `RuntimeHintsAgent`,
we need to load the java agent on the JVM and instrument test code to
check that invocations are properly recorded.
This commit adds the relevant build configuration to the
integration-tests module and adds reflection tests for the agent.
Closes gh-27981
This commit configures the `RuntimeHintsAgent` in the Spring Framework
test suite.
Instead of applying the agent to the entire test suite, and possibly
interfering with other tests, this commit adds a new custom Gradle
plugin that does the following:
* create a new test task named `"runtimeHintsTest"`
* run this task with the runtime hints java agent
* only execute tests tagged with `"RuntimeHintsTests"`
See gh-27981
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);
}
}
```
See gh-27981
With the introduction of `RuntimeHints`, we can now contribute
reflection, resources and proxies hints that describe the expected
runtime behavior of the application. While this can be verified at
runtime with smoke tests, managing such tests and compiling to native
there is not very efficient.
This commit introduces the new `RuntimeHintsAgent`, a Java agent that
instruments JDK methods related to `RuntimeHints`.
It is different from the GraalVM agent, which aims at collecting all the
required hints for the runtime behavior of an application and dump those
in the expected format.
Here, the `RuntimeHintsAgent` can collect the related invocations only
for a delimited scope (typically, a lambda within a test) and later
check those against a `RuntimeHints` instance. In the case of testing
`RuntimeHintsRegistrar` implementations, the process is reversed:
instead of manually checking for registered hints in a `RuntimeHints`
instance, tests should exercise the use cases and then check that the
recorded behavior is in line with the prepared hints.
This first commit adds the agent infrastructure that collects the
invocations for all relevant JDK methods.

Prior to this commit, if a cookie was added to MockHttpServletResponse,
the comment attribute was not included in the generated Set-Cookie
header. In addition, MockCookie.parse(String) did not support the
Comment attribute.
This commit addresses both of these issues.
Closes gh-28730
