- Update jackson.version from 2.21.1 to 3.1.0 - Change BOM import groupId from com.fasterxml.jackson to tools.jackson - Change jackson-databind groupId to tools.jackson.core (shared, eventcatalog) - Change jackson-dataformat-protobuf groupId to tools.jackson.dataformat (shared, runtime, client) - Rename spring-boot-jackson2 to spring-boot-jackson (runtime, client, query-support) - Keep jackson-annotations at com.fasterxml.jackson.core (backward compat in Jackson 3)

- Update all com.fasterxml.jackson.core imports to tools.jackson.core - Update all com.fasterxml.jackson.databind imports to tools.jackson.databind - Update all com.fasterxml.jackson.dataformat imports to tools.jackson.dataformat - Preserve com.fasterxml.jackson.annotation imports (compatibility) - JsonProcessingException -> JacksonException (unchecked) - SerializerProvider -> SerializationContext - JsonSerializer -> ValueSerializer - Module -> JacksonModule - BeanSerializerModifier -> ValueSerializerModifier - BeanDeserializerModifier -> ValueDeserializerModifier - BeanDescription -> BeanDescription.Supplier in modifier methods - StringDeserializer moved to deser.jdk subpackage - ObjectMapper -> JsonMapper for concrete instantiation - Remove throws IOException where JacksonException is now unchecked - Update SetupContext methods: addBeanSerializerModifier -> addSerializerModifier - Update SetupContext methods: addBeanDeserializerModifier -> addDeserializerModifier

- Package changes: com.fasterxml.jackson.core/databind/dataformat -> tools.jackson.* - JsonProcessingException -> JacksonException (unchecked), removed throws declarations - JsonMappingException -> DatabindException (unchecked), removed throws declarations - new ObjectMapper() -> new JsonMapper() - Jackson2ObjectMapperBuilderCustomizer -> JsonMapperBuilderCustomizer - Jackson2ObjectMapperBuilder -> JsonMapper.builder() pattern - builder.modulesToInstall/serializerByType -> SimpleModule + builder.addModule - ProtobufMapper/Schema imports updated to tools.jackson.dataformat.protobuf - com.fasterxml.jackson.annotation imports kept (backward compatible)

@copilot you have a compilation failure, pls continue the work

Error: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.15.0:compile (default-compile) on proj...

Fixed in e43fc2e. The compilation failure was caused by Jackson 3's JacksonException being unchecked (RuntimeException), making catch (IOException e) invalid where only Jackson operations were in the try block. Changes:

AkcesClientController: catch (IOException) → catch (JacksonException), removed throws IOException from deserialize()
AkcesDatabaseModelAutoConfiguration: Fixed customizer to use builder.addModule() instead of modulesToInstall()/serializerByType()
All test files: Replaced Jackson2ObjectMapperBuilder with JsonMapper.builder().addModule(...) pattern
Removed cascading try/catch IOException wrappers in DatabaseModelRuntimeTests and QueryModelRuntimeTests

Full mvn compile test-compile now passes across the entire project.

Pull request overview

Migrates the Akces framework (core modules + test apps) from Jackson 2 (com.fasterxml.jackson.*) to Jackson 3 (tools.jackson.*) and updates Spring Boot JSON customization to Spring Boot 4 / Spring Framework 7 conventions.

Changes:

Update Maven dependency management and module POMs to use the tools.jackson BOM and Jackson 3 artifacts (and spring-boot-jackson).
Replace Jackson 2 APIs/usages with Jackson 3 equivalents (exceptions, serializers/modifiers, mapper setup).
Update test utilities and auto-configurations to build/customize mappers via JsonMapper / JsonMapperBuilderCustomizer + SimpleModule.
