Jetty 12-only (GHSA range 12.0.0-12.0.31 / 12.1.0-12.1.5). The leaking code is Jetty 12's
GzipHandler/GzipRequest, where GzipRequest.destroy() (which returns the Inflater to the
pool) only ran through GzipResponseAndCallback when the response was also deflated. In
10.0.26, request inflation is a GzipHttpInputInterceptor (implements Destroyable)
installed on HttpInput. AsyncContentProducer.recycle() destroys it after every request,
whether or not the response is deflated.
