If you want to somehow process the details of the error message, you could:

• Use an XML text as the message, so you get a structured way:

  throw new UnhandledException(String.format(
      "Unexpected things%s", value), bthe);
  

• Use your own (and one for every case) exception types to capture variable information into named properties:

  throw new UnhandledValueException("Unexpected value things", value, bthe);
  

Or else you could include it in the raw message, as suggested by others.
