The JarScan and HistoPlotter tools are part of the JITWatch project: https://github.com/AdoptOpenJDK/jitwatch
Charts were produced using headless JavaFX (Monocle) with SwingFXUtils addition: http://chriswhocodes.com/#monocle
Caveat: For some of the projects I've scanned lib/*.jar which will catch some of the dependencies as well as the core code of these projects.
