In this paper we investigate the synchronization of multithreaded call graphs with reentrance similar to call graphs in Java programs. We model the individual threads as Visibly Pushdown Automata (VPA) and analyse the reachability of a state in the product automaton by means of a Context Free Language (CFL) which captures the synchronized interleaving of threads. We apply this CFL-reachability analysis to detect deadlock.
