I have bought Lucera2 from lucera2.ru at 2017-09-19 for 120 usd. The first thing i did was decompile jars and clean them up so they are usable like real source code. I have been working on those files for almost a year now and since my changes made it far superior, I have decided to share files in earliest stage.
Decompiling the files and cleaning them up have taken me a while, so I hope you will appreciate this share. You will not find that source code anywhere else on the internet.

1. In original jar there was a limit of active connections with game server, it was connected with GameServer variable "VALUES" and I have removed it.
2. I didn't find any backdoor, though I have removed all customs from the pack(in the revision that I will not share) so it could have been there and I have erased it.
