Let’s face it: if you’re a developer, a massive chunk of your time is probably spent on debugging. While development might only take up 20% of the process, the rest is usually about fixing issues, tracing paths, and reproducing bugs. Debugging large Java applications can be especially challenging and time-consuming, as you sift through complex flows and repeatedly retrace steps. But what if there was a way to make this easier?
Meet Java DebugX—an innovative Visual Studio Code extension designed to transform Java debugging with advanced features like macro recording and automated playback. Let’s dive into how Java DebugX can simplify the debugging process, saving you time and increasing productivity.
Setting Up Java DebugX in VS Code
To get started, ensure you have Visual Studio Code set up with the Red Hat Java Language Support and Lightweight Java Debugger extensions installed. These provide essential Java development and debugging support in VS Code.
Then, install Java DebugX from the marketplace. It’s as simple as searching for "Java DebugX" in the Extensions tab and clicking install. With Java DebugX, you’re ready to take debugging to a new level.
Recording a Debugging Session with Java DebugX
Once installed, you’ll see a "Start Recording" button in the Stack View navigation menu. Start a debugging session as usual and press "Start Recording." Java DebugX will automatically record your actions, including:
- Step in, step out, and step over actions
- Setting and removing breakpoints
- Continue and pause actions
Every action is saved in a macro format, allowing you to replay the session later. This can be invaluable if you’re debugging a complex flow and need to reproduce the exact sequence of actions without repeating each step manually.

Playing Back the Recorded Macro
After recording, you can play back the macro to revisit the debugging flow starting from the exact breakpoint where you initially began recording. Java DebugX allows you to control playback speed by setting java.debugx.macro.stepDelayInSeconds, adding delays between each automated playback step. Additionally, you can pause, resume, or stop the playback anytime using buttons in the Stacktrace Navigation Menu.

How Java DebugX Can Boost Productivity
Here’s a typical scenario: You’re debugging a large Java application and find a potential root cause. But after stepping forward, you realize you need to repeat the process to verify something. In a real-life setting, this is where Java DebugX shines—you can record the session once, then replay it up to the exact point you need to examine again.
Java DebugX even includes enhanced diagnostics to help when your macro takes a wrong path. If your playback reaches a point that differs from the expected line (like reaching an unexpected catch block or exception), DebugX will try to gather diagnostics and log them to a file, giving you a better understanding of potential issues.
Transforming Java Debugging with Java DebugX
With Java DebugX, debugging becomes faster, more manageable, and much less repetitive. This extension helps reduce human error and time spent on manual tasks, letting you focus on what matters—finding and fixing issues efficiently.
