When I try to assert an objecto to the working memory a exception is thrown. It seams that there is a problem when the shadow fact proxy. The detailed Exception trace is:

org.drools.RuntimeDroolsException: Error creating shadow fact for object: TemperatureSensor_1 [0.0]

I changed the default objenesis instantiator, because JamVM doesn't support Sun's ReflectionFactory class, but I can't find a solution
