The JITWatch user interface is built using JavaFX which is downloaded as a maven dependency for JDK11+.

For pre-JDK11 you will need to use a Java runtime that includes JavaFX.

maven

mvn clean package && java -jar ui/target/jitwatch-ui-shaded.jar

Build an example HotSpot log

# Build the code and then run
cd scripts && ./makeDemoLogFile.sh
