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);
}
}
```

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
This is needed as GraalVM 22.2 enabled the module system when building
native-images and all plugins have to participate in it.
See gh-28624
Closes gh-28732
Given the availability of two alternatives mechanisms for URL path
matching, PathPatternParser and AntPathMatcher, and now that
parsed patterns are enabled by default, it makes sense to reduce the
proliferation of options on AbstractHandlerMapping by deprecating
shortcuts related to String path matching. Most applications rely
on Boot and on the MVC config to do all this.
See gh-28607
MockHttpServletRequest now checks the requestURI and servletPath to
check whether they imply a Servlet path mapping, which is the case
when the requestURI is longer than the contextPath + servletPath.
This is essential when parsed patterns are in use in which case the
request path is parsed taking into account only the requestURI and
the contextPath. However, if the MappingMatch indicates a match by
Servlet path, then the servletPath is also taken into account.
See gh-28607
Commit d6768ccc18 introduced a regression in the support for merging
annotation attributes in a multi-level annotation hierarchy.
This commit addresses that issue by ensuring that a merged annotation
is once again synthesized if a meta-annotation in the annotation
hierarchy declares attributes that override attributes in the target
annotation.
Closes gh-28716
As gh-28624 supports only static boolean fields, we still
need a few classes to be initialized at build time.
Such explicit configuration should be in theory avoidable,
so we will work with the GraalVM team to see if this can be
fixed, see for example
https://github.com/oracle/graal/issues/4673
for HttpStatus.
See gh-28624
When the ProtocolResolver SPI was introduced in Spring Framework 4.3,
support for protocol resolvers was added in DefaultResourceLoader's
getResource() implementation; however, GenericApplicationContext's
overridden getResource() implementation was not updated accordingly.
Prior to this commit, if a GenericApplicationContext was configured
with a custom ResourceLoader, registered protocol resolvers were
ignored.
This commit ensures that protocol resolvers are honored in
GenericApplicationContext even if a custom ResourceLoader is used.
Closes gh-28703
