* add `Comparable` contract to the initial wrapper so that expressions containing selection/projection with JsonNode filtering are now possible * render directly the value of a ValueNode. SpEL parser can now evaluate correctly the object value when the expression deals with filtering on `JsonNode` values (<, >, ==...) * the 2 above changes make this possible: `property.^[name.getTarget().asText() == 'value1'].name` can now be written as simply as `property.^[name == 'value1'].name`. The expression is now fully compatible with other PropertyAccessor types * rename `ToStringFriendlyJsonNode` to `JsonNodeWrapper` as it reflects more the capability of the new wrapper * add a GenericConverter to be able to convert the `JsonNodeWrapper` class into a `JsonNode` (or its derivative classes) directly while calling `expression.getValue(..., JsonNode.class)` * add the possibility to access list items in a json-path like index => a negative number will begin from the end of the list <= * return null value when `JsonNode` cannot handle the property name (or index) * Change Json Converter * Clean up the code style * Convert JsonPropertyAccessor tests to JUnit 5

Checking out and Building
To check out the project and build from the source, do the following:
git clone git://github.com/spring-projects/spring-integration.git
cd spring-integration
./gradlew build
NOTE: While Spring Integration runs with Java SE 8 or higher, a Java 11 compiler is required to build the project.
To build and install jars into your local Maven cache:
./gradlew publishToMavenLocal
To build api Javadoc (results will be in build/api):
./gradlew api
To build the reference documentation (results will be in build/docs/asciidoc and build/docs/asciidocPdf):
./gradlew reference
To build complete distribution including -dist, -docs, and -schema zip files (results will be in build/distributions):
./gradlew dist
Using Eclipse
To generate Eclipse metadata (.classpath and .project files), do the following:
./gradlew eclipse
Once complete, you may then import the projects into Eclipse as usual:
File -> Import -> Existing projects into workspace
Browse to the 'spring-integration' root directory. All projects should import free of errors.
Using IntelliJ IDEA
To generate IDEA metadata (.iml and .ipr files), do the following:
./gradlew idea
