+/** ContinuationThrowable
+ * <p>
+ * A ContinuationThrowable is throw by {@link Continuation#undispatch()}
+ * in order to exit the dispatch to a Filter or Servlet.  Use of
+ * ContinuationThrowable is discouraged and it is preferable to 
+ * allow return to be used. ContinuationThrowables should only be
+ * used when there is a Filter/Servlet which cannot be modified
+ * to avoid committing a response when {@link Continuation#isSuspended()}
+ * is true.
+ * </p>
+ * <p>
+ * ContinuationThrowable instances are often reused so that the
+ * stack trace may be entirely unrelated to the calling stack.
+ * A real stack trace may be obtained by enabling debug.
+ * </p>
+ * <p>
+ * ContinuationThrowable extends Error as this is more likely
+ * to be uncaught (or rethrown) by a Filter/Servlet.  A ContinuationThrowable
+ * does not represent and error condition.
+ * </p>
