Description

When the response body is empty, e.g. when a FileNotFoundException is thrown by a generator, or servlet service call returns an empty response, a NPE is thrown by HttpServletResponseBufferingWrapper.

Patch adds a null check on HttpServletResponseBufferingWrapper's outputStream in the flushBufferedResponse method.
