Bytecode size histograms for popular Java-based projects

Published April 30th, 2016

Here are the bytecode histograms showing method size distributions for popular Java-based projects such as Android Studio, Scala, Groovy, Gradle, Eclipse, as well as the JDK and JavaFX.

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.
