I also read your article, sadly it describes nothing in detail. You talk much about theoretical stuff, which can be interesting, but is not what the article said it was about.
I know of course that you want to promote your super cool spatial search engine, but there isn't much information about that either.
So in the end, I don't really know what you are doing so special. Perhaps it is, but I can't know how it compares to normal simple data structures we already use in games.
I disagree with what you imply about Java not being a language designed for concurrency.
I think it is a valid point against Java, other languages have better constructs, rules and libraries to deal with concurrency.
