As of gh-33847, method and field introspection is included by default
when a type is registered for reflection.
Many methods in ReflectionHintsPredicates are now mostly useless as their
default behavior checks for introspection.
This commit deprecates those methods and promotes instead invocation
variants. During the upgrade, developers should replace it for an
`onType` check if only reflection is required. If they were checking for
invocation, they should use the new 'onXInvocation` method.
Closes gh-34239
This commit deprecates the `PathResource` implementation variant in
favor of `FileSystemResource`. This was already pointing to
`FileSystemResource` as of Spring Framework 5.1 and we now consider this
variant as deprecated.
Closes gh-34206
This commit fixes a regression in property placeholder resolution where
the original key was no longer considered for an exact match before
processing the placeholder itself.
By default, property resolution uses ':' as the separator between the
key and the fallback value.
Consider a request to resolve ${prefix://service}. Previously,
placeholder resolution would first attempt to resolve the raw text, that
is 'prefix://service', before attempting to resolve the 'prefix' key and
then use '//service' if the key did not resolve.
This commit restores that behaviour purely for backward compatible
reason.
Closes gh-34124
This commit updates the whole Spring Framework codebase to use JSpecify
annotations instead of Spring null-safety annotations with JSR 305
semantics.
JSpecify provides signficant enhancements such as properly defined
specifications, a canonical dependency with no split-package issue,
better tooling, better Kotlin integration and the capability to specify
generic type, array and varargs element null-safety. Generic type
null-safety is not defined by this commit yet and will be specified
later.
A key difference is that Spring null-safety annotations, following
JSR 305 semantics, apply to fields, parameters and return values,
while JSpecify annotations apply to type usages. That's why this
commit moves nullability annotations closer to the type for fields
and return values.

Properly processes recursive types through always comparing generics via the top-level ResolvableType (rather than through nested TypeDescriptors with custom ResolvableType instances).
Closes gh-33932
This metadata information is required for supporting libraries using
`sun.misc.Unsafe#allocateInstance(Class<?>)`, even though Spring
Framework is not using this feature.
Closes gh-34055
This commit fixes a regression in PlaceHolderParser where it would no
longer resolve nested placeholders for a case where the fallback has a
placeholder itself.
This is due to the Part implementations and how they are structure, and
this commit makes sure that nested resolution happens consistently.
Closes gh-34020
This commit adapts AOT support in various modules after the RuntimeHints
and related deprecation changes.
`MemberCategory.INTROSPECT_*` hints are now removed and
`MemberCategory.*_FIELDS` are replaced with
`MemberCategory.INVOKE*_FIELDS` when invocation is needed.
Usage of `RuntimeHintsAgent` are also deprecated.
Closes gh-33847
The `RuntimeHints` API mainly reflects what is needed to write GraalVM
reachability metadata. The latest GraalVM version simplified its
format. This commit applies relevant simplifications as parts of it are
not needed anymore.
The new metadata format implies methods, constructors and fields
introspection as soon as a reflection hint is registered for a type. As
a result, `ExecutableMode.INTROSPECT`, and all `MemberCategory` values
except `MemberCategory.INVOKE_*` are being deprecated.
They have no replacement, as registering a type hint is enough.
In practice, it is enough to replace this:
```
hints.reflection().registerType(MyType.class, MemberCategory.DECLARED_FIELDS);
```
By this:
```
hints.reflection().registerType(MyType.class);
```
As for `MemberCategory.PUBLIC_FIELDS` and `MemberCategory.DECLARED_FIELDS`,
values were replaced by `INVOKE_PUBLIC_FIELDS` and
`INVOKE_DECLARED_FIELDS` to make their original intent clearer and align
with the rest of the API. Note, if you were using those values for
reflection only, you can safely remove those hints in favor of a simple
type hint.
See gh-33847
As of GraalVM 23, a new and simplified reachability metadata format is
available. Metadata now consists of a single
"reachability-metadata.json" file that contains all the information
previously spread in multiple files. The new format does not include
some introspection flags, as they're now automatically included when a
hint is registered against a type.
Also, "typeReachable" has been renamed as "typeReached" to highlight the
fact that the event considered is the static initialization of the type,
not when the static analysis performed during native compilation is
reaching the type.
This new format ships with a JSON schema, which this commit is tested
against.
See gh-33847
Prior to this commit, the resource hints for AOT applications would
generate JSON metadata with `java.util.regex.Pattern`, like:
```
{
"resources": {
"includes": [
{
"pattern": "\\Qbanner.txt\\E"
}
]
}
}
```
This regexp feature, as well as "includes" and "excludes" are not supported
anymore with the new metadata format. This commit removes the pattern
format which is now replaced by a "glob" format.
"globs" should only contain "*" (zero or more characters in a path
segment) or "**" (zero or more path segments).
Some instances of resource hint registration should be migrated as a
result.
For example, "/files/*.ext" matched both "/files/a.ext" and
"/files/folder/b.txt" in the past. The new behavior matches only the
former, unless the "/files/**/*.ext" glob pattern is used.
This commit also removes the "excludes" support, which was not widely
used and very often could lead to subtle behavior.
Closes gh-31340
Prior to this commit, Spring Framework would allow two ways of getting
class metadata:
* `StandardClassMetadata`, using the Java reflection API
* `SimpleMetadataReaderFactory`, using ASM to read the class bytecode
This commit adds a new implementation for this feature, this time using
the new `ClassFile` API which is taken out of preview in Java 24.
See gh-33616
Before this commit, in Spring Framework 6.2, Kotlin value class
unboxing was done at CoroutinesUtils level, which is a good fit
for InvocableHandlerMethod use case, but not for other ones like
AopUtils.
This commit moves such unboxing to InvocableHandlerMethod in
order to keep the HTTP response body support while fixing other
regressions.
Closes gh-33943
Update `PathMatchingResourcePatternResolver` so that in addition to
searching the `java.class.path` system property for classpath enties,
it also searches the `MANIFEST.MF` files from within those jars.
Prior to this commit, the `addClassPathManifestEntries()` method
expected that the JVM had added `Class-Path` manifest entries to the
`java.class.path` system property, however, this did not always happen.
The updated code now performs a deep search by loading `MANIFEST.MF`
files from jars discovered from the system property. To deal with
potential performance issue, loaded results are also now cached.
The updated code has been tested with Spring Boot 3.3 jars extracted
using `java -Djarmode=tools`.
