/**
* ContinuationThrowable
*
* 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.
*
*
* 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.
*
*
* 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.
*
*
* @deprecated use Servlet 3.0 {@link javax.servlet.AsyncContext} instead
