A static path condition is a precise necessary condition for information flow between two program points. Previous work defined path conditions for procedural languages. Object oriented languages offer additional constructs such as dynamic dispatch, instanceof and exceptions. In this paper, we present an analysis of these constructs, which leads to precise path conditions operating only on the program's variables. This yields a gain in precision, allowing leverage of automatic constraint solving. We present details of path condition generation for Java constructs, and discuss preliminary insight from our prototype implementation.
