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.
