Bug: assertion fails when loading FSA

[HansvdLaan]

Whenever I load a Finite State Automaton: FiniteStateAutomaton automaton = (FiniteStateAutomaton)new XMLCodec().decode(new File("something.jff"), null);

I get the following error:

The FSA loads without problems with the assertion commented out.

I had fixed this is my local (older) version of jflap before I came across this project by simply commenting out the assertion. I have yet to experience any side effects.
