jitwatch's Introduction

JITWatch

Log analyser and visualiser for the HotSpot JIT compiler.

  • Video introduction to JITWatch video
  • Slides from my LJC lightning talk on JITWatch slides

For instructions and screenshots see the wiki

The JITWatch user interface is built using JavaFX. This is included in the Oracle JDK. If you are using a JDK that does not include JavaFX (e.g. Azul Zulu, or some flavour of packaged OpenJDK on Linux) then you can download a pre-built OpenJFX jar from https://chriswhocodes.com and put it in your build classpath.

ant

ant clean compile test run

maven

mvn clean compile test exec:java

gradle

gradlew clean build run

Build an example HotSpot log

# Build the code first with ant / maven / IDE
