This commits udpates ConverterFactory#getConverter to accept both
nullable and non-null T in the Converter return value.
Flexible nullability at ConverterFactory type level would have been
ideal, but is not possible due to how Kotlin deals with Class<T> when
T is nullable.
See gh-36063
This commit also replaces Arch Unit packageInfoShouldBeNullMarked() rule
by either configuring requireExplicitNullMarking = false when the whole
module does not have JSpecify annotations, or explicit @NullUnmarked
when some have and some don't.
See gh-36054
In gh-35947, the `Converter` contract was refined to allow for nullable
return values. This created a mismatch with the `ConverterFactory`
contract.
This commit fixes this mismatch by allowing nullable return values in
`Converter` instances created by `ConverterFactory`.
Fixes gh-36063
This includes MethodParameter resolving getParameterName() by default now.
initParameterNameDiscovery(null) can be used to suppress such resolution.
Closes gh-36024
The error message in such cases now indicates that the retry process
is being aborted preemptively due to pending sleep time.
For example:
Retry policy for operation 'myMethod' would exceed timeout (5 ms) due
to pending sleep time (10 ms); preemptively aborting execution
See gh-35963
Specifically, this commit introduces:
- timeout and timeoutString attributes in @Retryable
- a default getTimeout() method in RetryPolicy
- a timeout() method in RetryPolicy.Builder
- an onRetryPolicyTimeout() callback in RetryListener
- support for checking exceeded timeouts in RetryTemplate (also used
for imperative method invocations with @Retryable)
- support for checking exceeded timeouts in reactive pipelines with
@Retryable
Closes gh-35963
This commit revises the type-level nullability declaration in
ConvertingComparator in order to adapt to recent nullability changes in
Converter.
This commit also revises the workaround in commit 53d9ba879d.
See gh-35947
Add warnings to the class-level Javadoc for MergedAnnotations,
AnnotatedTypeMetadata, AnnotationMetadata, and MethodMetadata to point
out that annotations may be ignored if their attributes reference types
that are not present in the classpath.
Closes gh-35959
Allow defining converters that return non-null values by
leveraging flexible generic type level nullability in
org.springframework.core.convert.converter.Converter.
Closes gh-35947
In contrast to the previous commit, a warning similar to the following
is now logged in such cases.
WARN o.s.c.a.MergedAnnotation -
Failed to introspect meta-annotation @MyAnnotation on class
example.Config: java.lang.TypeNotPresentException:
Type example.OptionalDependency not present
See gh-35927
Prior to this commit, if a meta-annotation could not be loaded because
its attributes referenced types not present in the classpath, the
meta-annotation was silently ignored.
To improve diagnostics for such use cases, this commit introduces WARN
support in IntrospectionFailureLogger and revises AttributeMethods.canLoad()
to log a warning if a meta-annotation is ignored due to an exception
thrown while attempting to load its attributes.
For example, a warning similar to the following is now logged in such
cases.
WARN o.s.c.a.MergedAnnotation -
Failed to introspect meta-annotation @example.MyAnnotation on class
example.Config: java.lang.TypeNotPresentException:
Type example.OptionalDependency not present
This commit also improves log messages in AnnotationTypeMappings.
Closes gh-35927
For defensiveness against a singletonInstance/initialized visibility mismatch, we accept the locking overhead for pre-initialized null values (where we need the initialized field) in favor of a defensive fast path for non-null values (where we only need the singletonInstance field).
Closes gh-35905
This commit refines BindingReflectionHintsRegistrar with additional
dynamic hints for application-defined types, main core Java conversion
ones being already covered by ObjectToObjectConverterRuntimeHints.
