e response data returned synchronously by a JAX-RS resource,
 except that unmapped exceptions are not re-thrown by JAX-RS runtime to be handled by
 a hosting I/O container. Instead, any unmapped exceptions are propagated to the hosting
 I/O container via a container-specific callback mechanism. Depending on the container
 implementation, propagated unmapped exceptions typically result in an error status
 being sent to the client and/or the connection being closed.
