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.
