public class JavaDecisionBuilder
extends DecisionBuilder

This class acts as a intermediate step between a c++ decision builder and a java one. Its main purpose is to catch the java exception launched when a failure occurs during the Next() call, and to return silently a FailDecision that will propagate the failure back to the C++ code.
