PROFILE
Kate Anderson
Kate Anderson contributed to the newrelic/newrelic-java-agent repository, focusing on distributed tracing, release automation, and observability for Java applications. She engineered adaptive sampling algorithms and refactored tracing logic to improve efficiency and configurability, enabling dynamic adjustment of sampling rates based on traffic. Her work included building Redis and Jedis instrumentation, enhancing monitoring for Redis operations, and integrating robust CI/CD workflows using GitHub Actions and Gradle. By addressing compatibility with evolving Java versions and refining artifact publishing through Sonatype, Kate improved deployment reliability and trace accuracy. Her engineering demonstrated depth in Java, build automation, and distributed systems instrumentation.

Oct 1, 2025October 2025 performance summary for the newrelic/newrelic-java-agent focused on stabilizing distributed tracing behavior, improving sampling observability, and simplifying adaptive sampling configuration. Key work spanned a refactor of priority calculation for distributed tracing, removal of deprecated AdaptiveSampling, and enabling reservoir logging to better understand sampling and transaction events. These changes deliver clearer trace priorities, more reliable sampling decisions, and stronger observability with reduced maintenance burden.

Aug 1, 2025Month: 2025-08. Delivered Jedis 6.0.0 Redis instrumentation for the New Relic Java agent, enabling monitoring of Redis operations including Pub/Sub. This work included build/config updates, robust connection handling, and a refactored instrumentation layer to improve maintainability. Minor code hygiene improvements (import cleanup, removal of no-op weave methods) and license header updates were completed. Overall, this increases observability for Redis workloads, enabling faster issue diagnosis, more accurate performance analytics, and data-driven optimization decisions. Technologies demonstrated: Java, Java agent instrumentation, Redis/Jedis, build tooling, refactoring, license compliance.

Apr 1, 2025April 2025 focused on stabilizing runtime behavior and expanding configurable controls in the newrelic-java-agent. Delivered four items in newrelic/newrelic-java-agent: a Return Stack Processing Feature Flag with inline checks and a system-property toggle to address runtime errors during method node return stack processing; a defensive fix for Class Transformation AIOOBE adding a catch block, a warning, and removal of unused return stack processing code; a Scala 2.12 IllegalAccessError fix guarded by a feature flag with a precomputed IS_SCALA_212 flag to improve reliability of class version handling; and the New Relic Java Agent 8.21.0 release introducing CRaC, JDK24 support, sampling options, Undertow and Couchbase Client integrations, plus Netty and AWS Docker ID fetching fixes with a version bump. These changes collectively improve runtime stability, configurability, and release readiness, reducing customer incidents and expanding platform support.

Mar 1, 2025March 2025: Java 24 compatibility stabilization and test adjustments for newrelic/newrelic-java-agent. Implemented targeted fixes to address VerifyError in class loading by enhancing PatchedClassWriter's Throwable/Exception handling for newer ClassLoader changes; removed conditional Java security manager setting from JMS tests to align with Artemis/Java 8 compatibility; disabled ActiveMQ test for Java 24+ due to removal of Java Security Manager and evolving compatibility, pending resolution or migration to Java 8 baseline.
