2023 State of the Java Ecosystem Report Highlights: Java 17 Adoption, JDK Vendor Shifts, and Containerization Trends

New Relic recently released the "2023 State of the Java Ecosystem" report, providing background and insights into the current Java landscape based on performance data from millions of applications.

Key Findings

Java 17 adoption grew by 430% within a year, now used by over 9% of production applications.

Java 11 remains the most popular LTS version, with more than 56% of applications in production.

Java 8 usage fell to about 33%, down from 46% in 2022.

Java 7 is virtually obsolete, used by only 0.28% of applications.

Non‑LTS releases have very low adoption (1.6% overall), with Java 14 being the most popular non‑LTS version at 0.57%.

JDK vendors : Oracle’s share dropped from ~75% in 2020 to 28% in 2023, while Amazon Corretto rose to become the leading JDK provider with a 31% market share.

Containerization : 70% of reported Java applications run in containers.

Garbage collectors : The G1 collector remains the favorite for Java 11+ users (65% usage); newer collectors like ZGC and Shenandoah see limited adoption.

The report also notes factors influencing the decline of non‑LTS versions, such as lack of support, perceived feature value, and the time gap to the next LTS release.
