I work on java db engine. C/C++ and Java developers have completely different mind set. Where C guy is doing bite-wise operations Java guy will implement separate object for each pixel. It is rare to see tightly optimized java code. I see main Java advantage in concurrency and advanced programming. My code has fine-grained locking, robust, correct and very quickly written. And hand optimized code in bottlenecks usually has comparable speed.
