I fully expected the open source options to have a much larger market share. It was very surprising to see how many of our survey respondents are paying for Oracle JDK. On the OpenJDK vs OracleJDK front, things have changed a bit compared to JRebel's 2020 report which had commented: This indicates that people prefer stability rather than getting hold of all the latest bells and whistles. As the survey highlights, 37% of the developers taken the survey are still on the venerable version 8 (from 58% in 2020), although Java 11 with 29% (from 22% in 2020) is gaining ground. This is not what actually happens though. With a much faster release cycle after version 8, now touching version 18, you would expect that most would have migrated to a more recent version. Saying that another important index is Java version's adoption and whether Oracle JDK is preferred over OpenJDK. Systems that worked 20 years ago, written in Java 5, should be able to compile and run under version 8. The one that enterprises value most is backwards compatibility, being notoriously allergic to radical updates and upgrades. Look no further than the Fortune 500 list of companies reliance on it. Why has Java always been the favorite of enterprises?Įnterprises talked and still talk Java. Most importantly 31% of the sample worked in large Enterprise settings surpassing 1000 employees, therefore the report provides a very good indication of the usage of Java on an industrial level. It drew a total of 846 responses, half of them, and the majority, being developers, with the rest split between Java Architects, Team Leads, Directors, Consultants and Other. Overall developer productivity, including challenges and roadblocks.Popular frameworks, application servers, virtual machines, and other tools.CI/CD build times and commit frequencies.Trends in microservices adoption and usage.The new report which marked the 10th anniversary of JRebel's initiative, looks at the state of the Java ecosystem from the perspective of: So, "Where's Java Going In 2022", according to JRebel? The recent JRebel "Java Development Trends and Analysis 2022" report gave us the opportunity to revisit. It's been a while since our deep look into Java's ecosystem in "Where's Java Going In 2020".
