In telemetry, replace Objects.hash with HashingUtils.hash by dougqh · Pull Request #10813 · DataDog/dd-trace-java

dougqh · 2026-03-11T18:31:57Z

What Does This Do

Replaces calls to Objects.hash() with HashingUtils.hash() in the MetricCollector to avoid Object[] allocation from var-args call.

Motivation

Reduces Object[] allocation which reduces GC activity

Additional Notes

Updated two hashCode() method implementations in the MetricCollector inner classes to use HashingUtils.hash() instead of Objects.hash().
