JavaOp2 has moved from "iago's little project" to becoming a "Codethulu". Nobody knows what's all been done in there. For example, Tuberload is nowhere to be found right now and he was a co-writer way back when, as well as Ryan Marcus who has been gone for a while.
The best way to learn JavaOp and it's features is to read the code. I don't even know what it's all capable of!
Anyhow, I fixed that BNLS problem in beta43, and left backwards compatability, but fix your list because it's ugly and I'll probably remove it after a few more versions.
