Spbogie and I met in a chat on steam once...he described his (plan/intention) to convert ULib (and therefore allow ULX-like conversion) to Java/Minecraft.
I've no idea where he went with it, if ever started, etc.
I'm pretty sure he was wanting to see where MC Mod API went (which, unfortunately, really went nowhere over the past ~8 months it's been since I spoke with him).
Considering he was an integral team part to the original ULib UCL, I'd recommend asking him to throw in what he's got, whether it be actual code, idea framework, whatever.
