I'm no expert in this, but my understanding is that Java templates are 
purely for type management, and don't really provide much in the way of 
compile-time optimization (since they don't change the underlying memory 
allocation model of Java).  So it's not clear to me that rewriting JTS 
to use templates would provide optimal code via a direct port to C++.  
It might get closer, I guess, but maybe there'd still be some semantic 
rewriting required for maximum optimization. But I'd be happy for 
someone to prove this conjecture wrong  8^)
