Debugging Revolution with IntelliJ IDEA's Logpoints

Classic println debugging just got more powerful and faster.

1The Evolution of Println Debugging

Println debugging remains one of the most fundamental and frequently used debugging techniques by developers. IntelliJ IDEA's logpoint feature enhances this simple method with advanced capabilities. Logpoints offer conditional execution, stack trace printing, hit counters, and more while maintaining their original simplicity. The 2026.2 release introduces innovations that make this technique even more powerful.

2Next-Gen Debugging Infrastructure

IntelliJ IDEA 2026.2 brings a revolutionary infrastructure change for logpoints. Replacing traditional debugger-side evaluation with code instrumentation eliminates bottlenecks common in Java debuggers. This new approach delivers up to 30x performance improvements, particularly in hot paths. It enables precise results without compromising application performance during debugging sessions.

3AI Agent Integration

The new version offers better integration with coding agents. Agents can now reliably use logpoints and manage debugging sessions. While allowing agents to control their own logpoints, the IDE prevents accidental modification of user logpoints. New bundled capabilities enable agents to effectively utilize all logpoint features.

4Enhanced User Interface

Version 2026.2 introduces a new UI that simplifies logpoint setup to a single click. The console now tracks which logpoint produced each entry and allows easy navigation to the relevant code. Stack trace information can be viewed without cluttering the console with unnecessary messages. These features work in both local and remote JVM debug sessions.

5Performance Comparison

The traditional JPDA/JDWP breakpoint model paused the application for each trigger to evaluate conditions. This created significant bottlenecks in performance-critical code. The new instrumentation-based approach fundamentally solves this issue. Internal benchmarks show logpoints now perform as fast as regular print statements, making them reliable even in timing-sensitive code.

6Real-World Scenario

In gRPC server/client scenarios, traditional breakpoints might timeout and hide error states. Logpoints capture critical state information without pausing the application. Coding agents can automatically configure logpoints, summarize results, and identify bugs. This proves particularly valuable for debugging challenging issues in distributed systems.

7Terminal Execution Flexibility

Logpoint features aren't limited to the IDE - they're also accessible via terminal. Installed capabilities become available to any chosen agent. This provides developers with greater workflow flexibility. Agents work equally well through AI chat or the IDE's built-in terminal. Integration with agents like Claude Code further automates debugging processes.

8The Future of Debugging

IntelliJ IDEA's logpoint innovations herald a new era in debugging. They preserve the power of simple println debugging while addressing modern software development needs. With performance improvements, AI integration, and user-friendly interface, they're becoming indispensable tools for both beginners and experienced developers. These groundbreaking changes will continue to enhance software development productivity.
