/**
* An instance of <code>WriteOnReadException</code> is thrown by a
* thread whenever a write attempt is made to a VBox within a
* ReadOnlyTransaction.
*
* An application should never catch instances of this class, as the
* purpose of throwing an instance of this class is to make a
* non-local exit from the currently running transaction, and restart
* it with a new type of transaction that is able to deal with writes.
* This is done by the JVSTM runtime and should not be masked by the
* application code in anyway.
*
* The class <code>WriteOnReadException</code> is specifically a
* subclass of <code>Error</code> rather than <code>Exception</code>,
* even though it is a "normal occurrence", because many applications
* catch all occurrences of <code>Exception</code> and then discard
* the exception.
