100x is a pretty big exaggeration. Modern JVMs have just-in-time
compilation, so they're really running native machine code for the most
often used bits (badly optimised native code, but at least not directly
interpreted byte code)

IME good Java takes about 1.5 to 3 times what good C++ would. It depends
what you're doing of course, if the ap is heavily dependant on a database
that might be the bottleneck anyway.
