  Let O the basin of attraction of the unique stable equilibrium of a dynamical
system, which is the law of large numbers limit of a Poissonian SDE. We
consider the law of the exit point from O of that Poissonian SDE. We adapt the
approach of M. Day (1990) for the same problem for a Brownian SDE. For that
purpose, we will use the Large deviation for the Poissonian SDE reflected at
the boundary of O studied in our recent work Pardoux and Samegni (2018).
