In this blog, we highlight key findings from the 2025 Java Developer Productivity Report including remote development redeploy trends, AI usage, JDK adoption, and more.

JRebel is a productivity tool for Java developers that allows for instant code changes without restarting the application server or redeploying the application. By eliminating the need for server restarts during development, JRebel saves developers time and improves productivity, enabling rapid iteration and experimentation. Developers can learn how to integrate JRebel into their development workflow, streamline the development process, and accelerate the feedback loop when making code changes.

The 2025 Java Developer Productivity Report highlights the increasing importance of investing in Java tools despite economic challenges. AI tools are becoming essential for tasks such as code completion and debugging. However, remote development environments present redeploy time challenges. The report is based on a survey of 731 Java professionals, including developers and business leaders.

Highlights From the 2025 Java Developer Productivity Report

<p>its wild how AI tools went from nice to have to basically mandatory for devs in just 2 years. the redeploy time thing for remote envs is so real tho</p>
<p>what the report dont mention is the context quality issue. even with good AI tools ur still feeding the model generic context. we built <a href="http://github.com/rely-ai-org/caliber" target="_blank" rel="noopener nofollow">github.com/rely-ai-org/caliber</a> specifically to fix this for any codebase, not just java. gives ur ai tools actual repo awareness so suggestions are way more accurate</p>
