Architecture

A real-world experience report of migrating a medium-sized production plant and development organization to a Java 11-first approach.

This talk will describe how we took a Java 8-only plant and development environment and refreshed it to be Java 11 by default.

We will cover:

  • Overview of the New Relic environment and plant architecture
  • Build tools and in-house developed plugins and tooling
  • Migration to OpenJDK
  • Repo cleanup
  • Hunting regressions
  • Problems and stumbling blocks we encountered
  • Library upgrades and complex interdependencies
  •  Improvements and how we measured them
