This commit upgrades the CI pipeline with the following:
* replace JDK16 with JDK17 as build variant
* upgrade all JDK versions
* replace docker-image with registry-image resource for CI image
Although Java does not allow the definition of recursive annotations,
Kotlin does, and prior to this commit an attempt to synthesize a
merged annotation using the MergedAnnotation API resulted in a
StackOverflowError if there was a recursive cycle in the annotation
definitions.
This commit addresses this issue by tracking which annotations have
already been visited and short circuits the recursive algorithm if a
cycle is detected.
Closes gh-28012
Although the initial report in gh-28015 only covered inconsistencies
for arrays and strings in the toString() implementations for
annotations between the JDK (after Java 9) and Spring, it has since
come to our attention that there was further room for improvement.
This commit therefore addresses the following in toString() output for
synthesized annotations.
- characters are now wrapped in single quotes.
- bytes are now properly formatted as "(byte) 0x##".
- long, float, and double values are now appended with "L", "f", and
"d", respectively. The use of lowercase for "f" and "d" is solely to
align with the choice made by the JDK team.
However, this commit does not address the following issues which we may
choose to address at a later point in time.
- non-ASCII, non-visible, and non-printable characters within a
character or String literal are not escaped.
- formatting for float and double values does not take into account
whether a value is not a number (NaN) or infinite.
Closes gh-28015
This commit adds an API that lets individual components contribute code,
runtime hints, and protected access information. This ease the cases
where code need to be written in a privileged package if necessary and
let contributors provide hints for the code they generate.
Closes gh-28030
This commit repackages the Javapoet library into spring-core so that it
can be used by the AOT engine without requiring a specific version.
Closes gh-27828
Since the introduction of synthesized annotation support in Spring
Framework 4.2 (a.k.a., merged annotations), the toString()
implementation attempted to align with the formatting used by the JDK
itself. However, Class annotation attributes were formatted using
Class#getName in Spring; whereas, the JDK used Class#toString up until
JDK 9.
In addition, JDK 9 introduced new formatting for toString() for
annotations, apparently intended to align with the syntax used in the
source code declaration of the annotation. However, JDK 9+ formats enum
annotation attributes using Enum#toString instead of Enum#name, which
can lead to issues if toString() is overridden in an enum.
This commit updates the formatting used for synthesized annotations by
ensuring that toString() generates a string that is compatible with the
syntax of the originating source code, going beyond the changes made in
JDK 9 by using Enum#name instead of Enum#toString.
Closes gh-28015
Prior to this commit, WebTestClient only supported "lenient" comparison
of the expected JSON body.
This commit introduces an overloaded variant of `json()` in the
BodyContentSpec that accepts an additional boolean flag to specify
whether a "strict" comparison should be performed.
This new feature is analogous to the existing support in MockMvc.
