APMLP-1263 use TagMap.set in CoreTracer by dougqh · Pull Request #11106 · DataDog/dd-trace-java

dougqh · 2026-04-13T20:06:56Z

What Does This Do

Replaces a deprecated TagMap.put call with TagMap.set in CoreTracer when adding the profiling context engine tag to local root span tags.

Motivation

TagMap.put is deprecated in favor of TagMap.set for efficiency and API consistency with optimized tag map implementations. This aligns CoreTracer with the intended TagMap usage and addresses APMLP-1263.

Additional Notes

Scope is intentionally minimal: one call site in dd-trace-core/src/main/java/datadog/trace/core/CoreTracer.java.
Jira ticket: APMLP-1263

Testing

Checked the code diff to confirm only the targeted call site changed.
Attempted formatting via Format tool (./gradlew spotlessApply), but it failed in this sandbox due Gradle distribution download/network routing.
Ran Lint tool; it reported no configured linter auto-detected for the modified Java file.

Contributor Checklist
