摘      要：Java provides portability and safety at the price of efficiency. Many solutions have been proposed to overcome the lack of efficiency, but most of them lose either portability or the ability to dynamically load bytecode. The authors present a solution that reconciles all these factors. Harissa is an efficient environment for the execution of Java programs that permits mixing compiled and interpreted methods. Harissa s compiler translates Java bytecode to C, incorporating several aggressive optimizations an outperforming JIT systems by a factor of two or more.
