`PathMatchingResourcePatternResolver` is reflecting on
`org.eclipse.core.runtime.FileLocator` and invoking methods on it for
OSGi support. While this use case is highly unlikely in native images,
registering the reflection entry by itself should be enough.
Fixes gh-31271
This commit adds the relevant reflection hints required by
`KotlinDetector`; this class is trying to detect both `kotlin.Metadata`
and `kotlin.reflect.full.KClasses`.
Fixes gh- 31269
This new GraalVM feature replaces ConstantFieldFeature and
introduces various enhancements:
- Leverage the new FieldValueTransformer API
- Use GraalVM 22.3 graal-sdk dependency instead of svm one
- Avoid using internal GraalVM APIs
- No need to configure JPMS exports
- Directly integrated in spring-core module
- Simplified build configuration

This commit updates RuntimeHintsUtils to focus on registering a JDK
proxy only as annotations of annotated elements that have at least
an introspection hints are visible out-of-the-box.
This commit also removes unnecessary hints and adapt `@Reflective` to
detect if a hint is required using the introduced
MergedAnnotation#isSynthesizable.
See gh-28967
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
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
This commit leverages a subset of @philwebb initial experimentation
to compute at build time the value of specific boolean static fields
in native images. This enhancement is implemented for now as a
GraalVM feature.
The goal here is to keep an optimized footprint via build time code
removal without leveraging build-time class initialization which is known
for the blocking compatibility issues it introduces due to its viral nature.
For now, the static fields initialized at build time with native are:
- NativeDetector#imageCode
- Fields with a name ending by "Present" in "org.springframework" package
typically used for classpath check with ClassUtils#isPresent
Closes gh-28624
This commit adds a central utility to figure out if the application
must run with Ahead-Of-Time optimizations. This is mandatory for running
in a native image but can be selected on the JVM using the
"spring.aot.enabled" property.
This commit also introduces a utility that can be used to initialize a
context with generated artifacts. This represents the runtime
counterpart of ApplicationContextAotGenerator.
Closes gh-28474
Previously, Graal failed to build a native image as DataSize was
unintentionally initialized at build time. This commit workarounds the
faulty assumption by flagging it as safe to initialize at build-time.
Closes gh-28328
