The Extension of Kaffe to Analyse Runtime Characteristics of a Java Program

This paper describes an extension of Kaffe JVM which enables to extract runtime characteristics of a Java program. The runtime characteristics include frequency of method call instruction, ratio of library method call and ratio of method whose runtime is less than compile time. It also represents ratio of method called only once, polymorphicity of virtual call and distribution of method size called in runtime. This paper analyses runtime features of the SciMark benchmark suite using the extended Kaffe.
