FlowTracker - Track data flowing through Java programs

I'm excited to announce FlowTracker, a Java agent that tracks data flowing through Java programs. It helps you understand where any program got its output from, what it means, and why it wrote it.

Watch the video or explore the live demo yourself, and read how it works at https://github.com/coekie/flowtracker.

Some discussion about this on a Hacker News thread.
