Instrumentation of Java Bytecode for Runtime Analysis
Allen Goldberg, Klaus Haveland · NASA Technical Reports Server (NASA) · 2003
Abstract. This paper describes JSpy, a system for high-level instrumentation of Java bytecode and its use with JPaX, our system for runtime analysis of Java programs. JPaX monitors the execution of temporal logic formulas and performs predicative analysis of deadlocks and data races. JSpy’s input is an instrumentation specification, which consists of a collection of rules, where a rule is a predicate/action pair. The predicate is a conjunction of syntactic constraints on a Java statement, and the action is a description of logging information to be inserted in the bytecode corresponding to the statement. JSpy is built using JTrek an instrumentation package at a lower level of abstraction. 1
