JAX -- the Java Application eXtractor

JAX (short for "Jikes Application eXtractor") is an application extraction tool for Java that reduces the program's size. JAX extracts the necessary classes, methods, and fields from a Java application (or applet), applies some optimizations and compression techniques. We measured size reductions ranging from 30% to 80% on real-life Java applications, where the larger size reductions generally occur for large, library-based applications. We have succesfully used JAX on applications of up to 2000 classes.
