fix(spring): Support Spring Boot 4.1 by adinauer · Pull Request #5573 · getsentry/sentry-java · GitHub

📜 Description

Bump Spring Boot 4 to 4.1.0 and update the related OpenTelemetry dependency set to compatible releases:

OpenTelemetry SDK to 1.63.0
OpenTelemetry instrumentation to 2.29.0
OpenTelemetry semantic conventions to 1.42.0
Spotless to 8.6.0

Also keep the Spring 7 sample on the repository Kotlin compiler version when importing the Spring Boot BOM, and add Spring Boot 4.1.0 to the Spring Boot 4.x system-test matrix.

💡 Motivation and Context

Spring Boot 4.1.0 pulls newer OpenTelemetry dependencies than the previous Spring Boot 4 sample setup expected. This caused the Spring Boot 4 OpenTelemetry sample to fail at runtime with incompatible OpenTelemetry versions.

Fixes #5561

💚 How did you test it?

./gradlew :sentry-samples:sentry-samples-spring-7:compileTestKotlin --rerun-tasks --no-daemon
./gradlew spotlessApply apiDump --no-daemon
Built Spring Boot 4 sample artifacts and the Sentry OpenTelemetry agent
Ran Spring Boot 4 system tests for:
- sentry-samples-spring-boot-4
- sentry-samples-spring-boot-4-webflux
- sentry-samples-spring-boot-4-opentelemetry with agent auto-init enabled
- sentry-samples-spring-boot-4-opentelemetry with agent auto-init disabled; first run had a transient Kafka endpoint timeout, exact rerun passed
- sentry-samples-spring-boot-4-opentelemetry-noagent
- sentry-samples-spring-boot-4-otlp

📝 Checklist

I added GH Issue ID & Linear ID
I added tests to verify the changes.
No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
I updated the docs if needed.
I updated the wizard if needed.
Review from the native team if needed.
No breaking change or entry added to the changelog.
No breaking change for hybrid SDKs or communicated to hybrid SDKs.

🔮 Next steps

Bump OpenTelemetry and Spring Boot dependencies to compatible versions so the Spring Boot 4 OpenTelemetry sample works with Spring Boot 4.1. Keep the Spring 7 sample on the repository Kotlin compiler version when importing the Spring Boot BOM, and add Spring Boot 4.1 to the system test matrix.

LGTM, just some nits

LGTM! thanks for adding

Align the global Kotlin version with Spring Boot 4.1 and remove the now-unneeded Spring 7 BOM override. Also remove unused Spring 7-specific Kotlin aliases from the version catalog. Co-Authored-By: Claude <noreply@anthropic.com>

Move the Spring Boot 4 / OpenTelemetry dependency bump entry from 8.44.1 to the Unreleased section and add sub-list items showing each dependency version change. Co-Authored-By: Claude <noreply@anthropic.com>

The Spring 7 sample had two dependency issues causing compileTestKotlin to fail in the Spring Boot 4.x CI matrix: 1. Used libs.springboot.starter.test (Spring Boot 2.7.18) instead of libs.springboot4.starter.test, mixing Spring Framework 5.x test utilities with a Spring Framework 7.x runtime. 2. Missing Kotlin BOM import in dependencyManagement. Without it, Spring Boot 4.0.0's BOM downgraded kotlin-stdlib to 2.2.21 while the compiler and build tools remained at 2.3.21, causing ClasspathEntrySnapshotTransform initialization failures.
