Java Development in 2025: Evolving Priorities and Persistent Challenges -- ADTmag

Written by Perforce CTO Rod Cope and developer tools exec Jeff Michael, the "2025 Java Developer Productivity Report " reveals a landscape undergoing significant shifts, particularly in hiring trends, tooling budgets, and the adoption of new Java versions. Although enterprises continue to prioritize Java for their mission-critical applications, the report's authors found, economic headwinds and the complexities of modern development environments are pushing teams to do more with less. … Headcount and Budget: A Sign of the Times One of the most telling takeaways from this year's report is the cooling of Java hiring. In 2024, 60% of companies planned to add Java developers, the authors found. That's a number that has dropped to 51% in 2025. Similarly, the percentage of companies planning to increase their developer tool budgets has fallen from 42% in 2024 to 34% this year. Those numbers underscore what appears to be a tightening in development spending, a trend reflective of broader economic concerns. … JDK Upgrades: The LTS Migration is in Full Swing Another key trend surfaced in this report is the accelerated shift toward long-term support (LTS) versions of Java. A majority of respondents report using Java 17 (61%) and Java 21 (45%), marking a significant departure from the era where Java 8 and Java 11 dominated. ... Notably, many organizations continue to use unsupported Oracle distributions, with 35% still on Java 8 and 32% on Java 11. ... While IntelliJ IDEA remains the dominant IDE (84%), VS Code has now overtaken Eclipse as the second most-used IDE, with 31% of respondents using it, compared to Eclipse’s 28%. ... 42% of respondents reported using more than one IDE, with many IntelliJ IDEA users also leveraging VS Code for certain tasks. ... Remote Development and Cloud Adoption: Productivity vs. Latency With 51% of respondents working in remote or containerized development environments, cloud-based Java development is clearly on the rise, the authors concluded. However, this transition is not without challenges. Redeploy times in cloud environments remain a major productivity bottleneck, with 27% of developers experiencing redeploys of 10+ minutes. That's a stark contrast with the sub-two-minute redeploy times common in local environments. Interestingly, cloud provider choice plays a role in these delays. 60% of AWS users reported redeploy times of five minutes or longer, whereas Microsoft Azure (53%) and Google Cloud Platform (43%) fared slightly better. This could indicate that companies need to consider not just cost and features when choosing a cloud provider but also the impact on developer efficiency, the authors warned … AI-powered coding tools are no longer a novelty. They’re becoming a staple in Java development. Only 12% of respondents reported not using AI tools, while another 12% said their companies prohibit AI use. The rest? They're embracing AI-powered assistance, with GitHub Copilot (42%) and ChatGPT (52%) being the most commonly used AI tools. Developers are primarily leveraging AI for code completion (60%) and refactoring (39%), with growing adoption for debugging, documentation generation, and automated testing. However, concerns about AI accuracy and security remain, particularly for enterprise developers, who show a clear preference for development-specific AI tools over generic AI chatbots. Final Thoughts: Productivity in an Era of Constraints The "2025 Java Developer Productivity Report "paints a picture of an industry facing economic constraints, cloud development challenges, and the growing complexity of modern architectures. But the report also highlights opportunities for teams willing to embrace AI, optimize their tooling, and strategically navigate their cloud and architecture choices." "While economic uncertainty remains, the value of investing in Java remains steadfast as the language celebrates its 30th birthday this year, Cope wrote.
