This game - workshop - will be set of miss-behaving java programs, where attendees will be given runtime java reverse engineering tools and some quick introduction how to use them.
The goal will be to hot-patch and fix those programs as quickly as possible in most complicated way (obfuscated, without debuginfo)... well... to fix them at all if possible.

A prerequisite is need to have at least jdk11 and jdk17 on own laptop, where the game will be played
