Prior to this commit, resource handling would not serve empty files and
return instead HTTP 404 responses. This would only happen for files
contained by JARs, but not on the filesystem.
This can be tracked to changes done in `AbstractFileResolvingResource`
where we avoid serving empty files for directories, see gh-21372.
This commit improves the `checkReadable` method to align this behavior
between file system and JAR files.

Prior to this commit, the following exception was thrown when using the
PathMatchingResourcePatternResolver to scan for class path resources
using the `classpath*:` prefix within a native image.
com.oracle.svm.core.jdk.UnsupportedFeatureError: JRT file system is disabled
com.oracle.svm.core.util.VMError.unsupportedFeature(VMError.java:89)

org.springframework.core.io.support.PathMatchingResourcePatternResolver.lambda$findAllModulePathResources$6(PathMatchingResourcePatternResolver.java:819)
This commit addresses this by not attempting to scan the module path
when running in a GraalVM native image.
Closes gh-29183
In preparation for gh-29163, this commit revamps
PathMatchingResourcePatternResolverTests as follows.
- organizes tests into @Nested test classes
- reintroduces the @Disabled classpathStarWithPatternOnFileSystem() test
- stops asserting the protocol of Resource URLs, since the protocol is
dependent on the environment -- for example, file: and jar: URLs are
actually resource: URLs within a GraalVM native image
- simplifies implementation of test methods and assertFilenames()
Previously, only the first occurance of `@Reflective` and its
processor was considered. When `@Reflective` appeared twice on a type
due to meta-annotations or inheritance, this resulted in other
processors being ignored and hints were missing as a result.
This commit updates ReflectiveRuntimeHintsRegistrar to consider
every occurance of `@Reflective` found in the type hierarchy,
and to then use the processors from each of them.
Fixes gh-29193
gh-28506 introduces a big footprint regression on
native, so it should for now be skipped when
compiling to native images. Such support could
potentially be re-introduced via gh-29081.
Closes gh-29183
This commit fixes an issue in StringDecoder, where, if the buffer did
not contain any delimiters, it was released before it was relayed to
any subscribers.
Closes gh-29119
This commit adds predicates variants that accept `String className`
instead of actual `Class<?>` when checking for fields and method hints.
This is useful when the type under test is not visible from the current
test class.
Closes gh-29143
Prior to this commit, the Javadoc for the getPath() method in
ClassPathResource stated the following.
> Return the path for this resource (as resource path within the class path).
That implied the returned path was an "absolute path" within the class
path; however, that was not always true.
If the resource was created using ClassPathResource(String) or
ClassPathResource(String, ClassLoader), the returned path was a cleaned
version of the ABSOLUTE PATH supplied to the constructor, WITHOUT a
leading slash.
If the resource was created using ClassPathResource(String, Class) with
an absolute path, the returned path was a cleaned version of the
ABSOLUTE PATH supplied to the constructor, WITH a leading slash.
If the resource was created using ClassPathResource(String, Class) with
a relative path, the returned path was a cleaned version of the
RELATIVE PATH supplied to the constructor.
In addition, ClassPathResource does not provide public access the Class
passed to the ClassPathResource(String, Class) constructor.
Consequently, the path returned by getPath() could not be reliably used
with ClassLoader.getResource(String) or with the recently introduced
registerResource(Resource) method in ResourceHints.
This commit addresses this issue by ensuring that getPath()
consistently returns the absolute path within the class path without a
leading slash.

Previously, a shortcut method for the default ExecutableMode was
provided, but we found out that the shortcut makes it harder to
determine the intent.
This commit harmonizes hints registration for types, methods, and
fields. An ExecutableMode is now mandatory to register a method or
constructor. Previous methods that infer a mode or provided a
customizer of the builder are deprecated.
Closes gh-29135
In recent GraalVM versions, allowWrite and allowUnsafeAccess have been
deprecated and are no longer use. This commit updates FieldHint to
remove the irrelevant properties.
See gh-29130
Update StreamUtils.drain to use InputStream.transferTo with a null
OutputStream. This avoids allocating buffers for cases where the
supplied InputStream has an optimized transferTo method (e.g.,
ByteArrayInputStream and FileInputStream).
Additionally, update StreamUtils.emptyInput to simply call
InputStream.nullInputStream.
Closes gh-28961
This commit records `@PropertySource` declarations defined on
configuration classes so that these are contributed to the environment
of a context that is initialized by generated code.
Closes gh-28976
This commit moves MethodReference to an interface with a default
implementation that relies on a MethodSpec. Such an arrangement avoid
the need of specifying attributes of the method such as whether it is
static or not.
The resolution of the invocation block now takes an
ArgumentCodeGenerator rather than the raw arguments. Doing so gives
the opportunity to create more flexible signatures.
See gh-29005
This commit updates GeneratedMethod and its underlying infrastructure
to be able to produce a MethodReference. This simplifies the need when
such a reference needs to be created manually and reuses more of what
MethodReference has to offer.
See gh-29005
This commit renames registerResourceIfNecessary() to registerResource()
and throws an exception if the class path resource does not exist.
Closes gh-29083
This aligns the buffer size used in StreamUtils with the buffer sizes
used throughout the JDK (see InputStream, BufferedInputStream, Files).
Closes gh-28965
As of Java 18, the serial lint warning in javac has been expanded to
check for class fields that are not marked as `Serializable`.
See https://www.oracle.com/java/technologies/javase/18all-relnotes.html#JDK-8202056
In the Spring Framework codebase, this can happen with `Map`, `Set` or
`List` attributes which are often assigned with an unmodifiable
implementation variant. Such implementations are `Serializable` but
cannot be used as field types.
This commit ensures that the following changes are applied:
* fields are marked as transient if they can't be serialized
* classes are marked as `Serializable` if this was missing
* `@SuppressWarnings("serial")` is applied where relevant
Prior to this commit, the `RuntimeHintsAgent` and its testing
infrastructure would assume that calling `MyClass.class.getMethods()`
requires a reflection hint on the class for introspecting public/private
methods.
GraalVM does not require this, in fact this call only returns methods
that have reflection hints in the native image.
This commit refines the agent behavior for `Class.getMethods()`,
`Class.getDeclaredMethods()`, `Class.getFields()` and
`Class.getDeclaredFields()`. With this change, registering at least one
method/field for reflection is enough to match.
During the execution of Java tests, all methods and fields will be
provided, regardless of hints being registered or not. This could cause
false negatives where we're missing reflection hints on methods or
fields.
This risk is mitigated thanks to additional instrumentation on
`Method.getAnnotations()`, `Method.getParameterTypes()` and
`Method.invoke()`. If a method is found reflectively, chances are it
will be used for further reflection.
