ObjectUtils.nullSafeToString(Object) exists for generating a string
representation of various objects in a "null-safe" manner, including
support for object graphs, collections, etc.
However, there are times when we would like to generate a "concise",
null-safe string representation that does not include an entire object
graph (or potentially a collection of object graphs).
This commit introduces ObjectUtils.nullSafeConciseToString(Object) to
address this need and makes use of the new feature in FieldError and
ConversionFailedException.
Closes gh-30286
StringUtils.truncate() serves as central, consistent way for truncating
strings used in log messages and exception failure messages, for
immediate use in LogFormatUtils and ObjectUtils.

This commit refactors some AssertJ assertions into more idiomatic and
readable ones. Using the dedicated assertion instead of a generic one
will produce more meaningful error messages.
For instance, consider collection size:
```
// expected: 5 but was: 2
assertThat(collection.size()).equals(5);
// Expected size: 5 but was: 2 in: [1, 2]
assertThat(collection).hasSize(5);
```
Closes gh-30104
This commit adds a reflection hint for HttpMethod#valueOf in order
to be able to support conversion required for Spring Boot
configuration properties binding as described in
https://github.com/spring-projects/spring-boot/issues/34483.
Closes gh-30201
This commit reverts the changes done via 50a0094a47
in order to ensure consistency across modules (those changes were specific to
spring-core).
Reproducible builds are likely desirable, but it is a complex topic
(see gradle/gradle#14819) that needs to be addressed portfolio wide, with
a better control than what Gradle currently allows (for example to allow
using EPOCH instead of the current 1980 date).
Basic tests did not show an obvious impact on testing avoidance with modern
Gradle versions.
Closes gh-29633
Before this commit, anonymous classes could throw an
unexpected NullPointerException in
ReflectionsHint#registerType and lambdas entries could
be created in the related generated reflect-config.json.
This commit refines how anonymous classes are handled by
explicitly checking for null class and canonical name in
ReflectionTypeReference#of, while skipping such class in
ReflectionHints#registerType in order to keep a lenient
behavior.
Closes gh-29774
This commit refines CoroutinesUtils#invokeSuspendingFunction in order
to clarify the behavior when used on a non suspending function, and
support usages with or without the Continuation argument.
Closes gh-30005
This commit makes several changes to PR #24651.
- Add byte[] getContentAsByteArray() on Resource.
- Remove getContentAsString() from Resource, as it relied on the default
charset which is not reliable.
- Add getContentAsString() to EncodedResource, as a charset is provided
through the constructor.
See gh-24651
This commit introduces DataBuffer::readableByteBuffers and
DataBuffer::writableByteBuffers, allowing restricted access to the
ByteBuffer used internally by DataBuffer implementations.
Closes gh-29943
Originally, `Base64Utils` was providing base64 encoding and decoding
utilities, bridging to commons-codecs or Java 8, if available. Since
then, only the Java 8 variant remains and Spring Framework 6 requires
now Java 17. This utility class doesn't provide additional checks or
syntactic sugar over what's in Java already.
As a result, this commit deprecates this class in favor of `Base64` and
schedules the removal of this class completely.
Closes gh-28434
Prior to this commit, `ConcurrentReferenceHashMap` subclasses extending
`Reference` would call `Reference::clear` right next to
`Reference::enqueue`; this is not needed as the latter calls it already.
Closes gh-28863
The "manipulating property sources" example in the Javadoc for
`ConfigurableEnvironment` states that `MutablePropertySources`
expect a `Map<String,String>`; whereas it expects a
`Map<String,Object>`.
Closes gh-29693
Prior to this commit, there was a bug in the implementation of
StandardRepeatableContainers.computeRepeatedAnnotationsMethod() which
has existed since Spring Framework 5.2 (when
StandardRepeatableContainers was introduced). Specifically,
StandardRepeatableContainers ignored any repeatable container
annotation if it declared attributes other than `value()`. However,
Java permits any number of attributes in a repeatable container
annotation.
In addition, the changes made in conjunction with gh-20279 made the bug
in StandardRepeatableContainers apparent when using the
getMergedRepeatableAnnotations() or findMergedRepeatableAnnotations()
method in AnnotatedElementUtils, resulting in regressions for the
behavior of those two methods.
This commit fixes the regressions and bug by altering the logic in
StandardRepeatableContainers.computeRepeatedAnnotationsMethod() so that
it explicitly looks for the `value()` method and ignores any other
methods declared in a repeatable container annotation candidate.
Closes gh-29685
This commit ensures that giving an anonymous class for reflection hints
registration does not result in a NullPointerException, since the
canonical name of anonymous classes is null.
Fixes gh-29657
Prior to this commit, the `ConcurrentLruCache` implementation would use
arrays of `AtomicReference` as operation buffers, and the buffer count
would be calculated with the nearest power of two for the CPU count.
This can result in significant heap memory usage as each
`AtomicReference` buffer entry adds to the memory pressure. As seen in
FasterXML/jackson-databind#3665, this can add a significant overhead for
no real added benefit for the current use case.
This commit changes the current implementation to use
`AtomicReferenceArray` as buffers and reduce the number of buffers.
JMH benchmarks results are within the error margin so we can assume that
this does not change the performance characteristics for the typical use
case in Spring Framework.
Fixes gh-29520
