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.

<h2>maven</h2>
<pre>mvn clean package && java -jar ui/target/jitwatch-ui-shaded.jar</pre>

<h2>Build an example HotSpot log</h2>
<pre># Build the code and then run
cd scripts && ./makeDemoLogFile.sh</pre>
