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
