* This exception is provided as a way for API users to throw
* exceptions from their event handling code. By doing so they
* abort file processing by the HSSFEventFactory and by
* catching it from outside the HSSFEventFactory.processEvents
* method they can diagnose the cause for the abort.
*
* The HSSFUserException supports a nested "reason"
* throwable, i.e. an exception that caused this one to be thrown.
*
* The HSSF package does not itself throw any of these
* exceptions.
