After having compiled the program 'c:\javac StateMachineTest.java' and executing it 'c:\java StateMachineTest' the following appeared on screen:

begin screen dump:

A nonfatal internal JIT (3.00.078(x)) error 'LD: null preHeader' has occured in:
'StateMachineTest.main ([Ljava/lang/String;)V' : Interpreting method.

Please report bug to.......

end screen dump.

I hope this is of some use to you.

Here is the source code for StateMachineTest:

       return true; // end if

    else // start else
       return false; // end else

  } // end PointTest

    if(TestString[counter] == "0" || // start if
