Unfortunately, SimState's code isn't helpful here -- it didn't attach the cause of the InvocationTargetException so you could see what's going on.  I just committed a new version of SimState.  try grabbing MASON from the repository and running it again.  Or you could just edit line 365 of SimState.java to say:

throw new RuntimeException("Exception occurred while trying to construct the simulation " + c, e);
