Resolution: Fixed
> ExportTest fails on JDK 17 after camel-spring-boot moved to Spring Boot 4

> Key: CAMEL-23213
> URL: https://issues.apache.org/jira/browse/CAMEL-23213
> Project: Camel
> Issue Type: Bug
> Components: camel-jbang
> Reporter: Guillaume Nodet
> Assignee: Guillaume Nodet
> Priority: Major
> Fix For: 4.19.0

>
> camel-spring-boot 4.19.0-SNAPSHOT moved to Spring Boot 4, which requires JDK
> 21. The camel-catalog-provider-springboot artifact is now compiled with Java
> 21 bytecode (class file version 65.0).
> This causes two issues:
> 1. *CI failures*: ExportTest and other tests that parameterize over
> RuntimeType.springBoot fail on JDK 17 runners with:
> {code}
> UnsupportedClassVersionError:
> org/apache/camel/springboot/catalog/SpringBootRuntimeProvider has been
> compiled by a more recent version of the Java Runtime (class file version
> 65.0), this version of the Java Runtime only recognizes class file versions
> up to 61.0
> {code}
> This affects any PR whose incremental CI pulls in camel-jbang-core on JDK 17.
> Confirmed on multiple PRs (CAMEL-23209, CAMEL-23212, CAMEL-23210, etc.).
> 2. *User-facing*: {{camel jbang export --runtime=spring-boot}} fails on JDK
> 17 with an unhelpful UnsupportedClassVersionError.
> *Fix*:
> - CatalogLoader.loadSpringBootCatalog() catches UnsupportedClassVersionError
> and provides a clear error message guiding the user to use
> {{--camel-spring-boot-version=4.18.x}} for JDK 17 compatibility, or upgrade
> to JDK 21+.
> - Tests skip Spring Boot runtime type on JDK < 21.
> *Note*: Reverting camel-spring-boot to compile with JDK 17 would not help,
> since Spring Boot 4 itself requires JDK 21 — users on JDK 17 cannot run
> Spring Boot 4 applications anyway.
