Throw warning if ServletInputStream.transferTo(OutputStream) is used while in Async ReadListener is in use? #11663

Open joakime opened 3 months ago

joakime commented 3 months ago

Jetty version(s) 12.0.8

Enhancement Description

If a Servlet is in an active ReadListener mode (Async Read), and there is code that attempts to use ServletInputStream.transferTo() style methods (that result in multiple read attempts) then it I think using that method should throw an IllegalStateException indicating that this method is unsupported during ReadListener operations.
