I didn't say it. You said D was as fast as C now. Then, according to your definition of "as fast as C", Java must be fast as C as well. Seems your as fast as C

I didn't say it. You said D was as fast as C now. Then, according to your definition of "as fast as C", Java must be fast as C as well. Seems your as fast as C definition must be something between 30%-95% performance of C because those are the most common performance numbers reported for D in various benchmarks (I cited one of them, and the one in the blog also confirms this - only one D compiler managed to match the best C compiler, the others were significantly behind). The same numbers are consistently reported about Java, so I don't really understand what you're arguing about. So I conclude both are the same league (with two minor exceptions: 1. I saw Java beating GCC many times, once quite severely by almost 2x on simple array numerical code, while I never saw that happening for D and 2. D has much worse GC implementation than Java or C# have).
