Hello WaterWolf, this isn't an issue, just me trying to contact you. I looked for your email but was unable to find it, so I'll just open an issue instead.

I'd just like to let you know that I've used some of the base of J-RET for a project of mine called BCV - https://github.com/Konloch/bytecode-viewer

I think you'll be really happy to see J-RET is still being maintained and worked on! If you would like to talk more feel free to email me at konloch@gmail.com
