The Java ecosystem is vast and diverse, making it difficult to draw a single conclusion about its market. However, by analyzing data from tens of millions of Java virtual machines (JVMs) that share their data with New Relic, researchers have gained insights into the state of the Java ecosystem. The most popular Java version used in production environments is still Java 8, but there is a growing acceptance of non-Oracle Java vendors, such as AdoptOpenJDK. The adoption rate of Java 11 is increasing, and it has become the second most popular vendor after Oracle. Garbage collection algorithms also vary widely among different JVM versions, with CMS being more popular than G1 on Java 8, while ZGC is significantly less popular on Java 11. Heap size configurations are relatively small, with only a few percent of systems using heaps larger than 16GB. The "pinned heap" flag combination is still widely used, but it can be counterproductive for modern workloads. Overall, the data provides a snapshot of the Java ecosystem and highlights areas where improvement is needed.
