JITWatch is a log analyser and visualiser for the Java HotSpot JIT compiler, built with a JavaFX user interface. It lets developers inspect inlining decisions, hot methods, bytecode, and generated assembly from JIT compilation logs.
Use cases
- analyze hotspot jit compiler logs
- inspect method inlining decisions in java
- find hot methods in my java application
- view bytecode and assembly generated by the jit
- understand why the jit did not inline a method
- visualize escape analysis results
- tune java performance using jit logs
When to choose
- you need to understand HotSpot JIT compilation behavior for performance tuning
- you want a GUI to explore inlining decisions, hot methods, and generated assembly
- you are profiling Java applications at the JIT level
When to avoid
- you need general application profiling rather than JIT-specific analysis
- you work outside the JVM/HotSpot ecosystem
- you prefer command-line-only tooling without a JavaFX GUI
