It is not a clone, at least not a clone of the recent code. The code is obfuscated (probably proguard?) and I don't have time to dig further, but seems to be using a lot of third party libraries that we [Nxt] don't use. Uses jetty, and json-simple, but also jackson and mapdb, no H2.
The developer has definitely borrowed ideas from Nxt, but probably not much from the current implementation.
As for the speculations that it may be BCNext himself - not his style, remember the original Nxt code did not use any other libraries (even the jetty dependency was added later by CfB) and was a single file. It is more likely a good java developer who started from the original Nxt 0.4.x code like I did, but then continued his own way into a completely different implementation. But all this may have been intentional, to confuse people - so the conspiracy theories will keep going on.
