Abstract

Presents a detailed characterization of Java application and applet workloads in terms of reuse and sharing of Java code at the program, class and method level. In order to expose more sharing opportunities, techniques for detecting code equivalence (even in the presence of minor code changes or constant pool index differences) are also proposed and examined. The analyzed application workload consists of the recently released SPECjvm98 benchmarks, and the applet workload is derived from three extensive searches of the Internet between May 1997 and May 1998 using an enhanced Web crawler. Analysis of these workloads reveals several new code sharing and optimization opportunities
