Read Original

This technical article dives into the undocumented file format of JDK Flight Recorder (JFR), a Java profiling tool. It explains the lack of an official specification, describes the author's process of reverse-engineering the format using source code and a hex editor, and discusses the utility of this knowledge for building analysis tools in other languages or repairing corrupted files.
