JIT Tree

This tool will help you to analyze the output of the JVM's -XX:+LogCompilation option.

To enable this option you also need to pass: -XX:+UnlockDiagnosticVMOptions to the program under JIT logging.

Optionally you can specify the name of the output file with -XX:LogFile=FILENAME, the default is hotspot.log.

The parsing of the output is done with OpenJDK's LogCompilation tool with small modifications.

Build

mvn clean package

Run

Double-click on target/jittree.jar

or

java -jar target/jittree.jar <logfile>

Requirements

I have only tested it with the output of JDK version 1.7.0_07.
