March 2, 2021
Java agent v6.4.2

Fixes

Fixes an issue that could cause some instrumentation modules (e.g. jax-rs-1.0) to have a WeaveViolation and not apply properly.

February 2, 2021
Java agent v6.4.1

Fixes

Fixes an issue in 6.4.0 where spans would not get sent to Infinite Tracing.

January 27, 2021
Java agent v6.4.0

Note:

  • There is an issue with this agent release that could lead to spans not being sent to Infinite Tracing. Please use 6.4.1 instead.

New Features and Improvements:

  • Spring Webflux/Netty Reactor instrumentation improvements for enhanced tracing across asynchronous thread hops.
  • The agent will now utilize a backoff sequence on connection retries to Infinite Tracing.
  • New distributed tracing APIs have been added to better support general use cases for propagating distributed tracing headers. In particular the new APIs provide enhanced support for W3C Trace Context but are flexible enough to support other header protocols that may be supported by the agent in the future. Previous distributed tracing APIs have been deprecated and are subject to removal in a future agent release. See documentation here.

Fixes:

  • Updated the Java agent’s snakeyaml dependency to 1.27.
  • In some environments the jar collector service could lead to high CPU utilization at application startup. The agent now provides a configurable rate limiter, with a reasonable default, for processing jars detected in the application’s environment. See documentation here.

Support statement:

  • New Relic recommends that you upgrade the agent regularly to ensure that you're getting the latest features and performance benefits. Additionally, older releases will no longer be supported when they reach end-of-life.

December 17, 2020
Java agent v6.3.0

Improvements

  • Spring Webflux
    • The Java agent now supports Spring Webflux versions 5.3+
    • Added reactor-netty.errors.enabled configuration to allow disabling error reporting in Subscriber::onError.
  • Scala 2.13
    • The Java agent now provides support for Scala 2.13 and frameworks compiled with 2.13 Akka-http, Play

Fixes

  • The netty-4.0.8 instrumentation would sometimes not start a Transaction on channelRead, potentially affecting instrumentation dependent on it including: Spring, Akka and Play
  • Updated the Java agent’s Apache HttpClient dependency to 5.13
  • Spring Webclient could report the wrong URL when multiple HTTP calls to several URLs occurred in parallel

November 17, 2020
Java agent v6.2.1

Fixes

  • Fixes an issue where Spring-Webflux applications with endpoints returning Flux or empty content could become unresponsive

November 10, 2020
Java agent v6.2.0

New features

return serviceA.getData()
.map(service -> Response.builder().service(service).build())
.flatMap(serviceB::getData)
.flatMap(serviceC::getData)
.doOnNext(this::saveResponse);

Improvements
