How does this support come now with alpn-boot not in picture? For example, one of the support we use in our code with ALPN is setting the DEBUG flag to true as follows: > org.eclipse.jetty.alpn.ALPN.debug = true Because with 8u252 or later the Jetty ALPN boot jar and API are not used, there will be no point in setting `org.eclipse.jetty.alpn.ALPN.debug = true`: you don't have the class in the classpath, and even if you put it back it will have no effects because it's not used anyway. -- Simone Bordet ---- http://cometd.org http://webtide.com Developer advice, training, services and support from the Jetty & CometD experts.
