This is the mailing list for the JITWatch HotSpot log file analyser hosted at https://github.com/AdoptOpenJDK/jitwatch

Feel free to discuss anything related to JITWatch, Just-In-Time compilation, the JVM, bytecode, and performance tuning in general.

Bugs, feature requests, and general usage questions are all welcome.

Let's learn from each other!

Cheers,
