Re: [jetty-dev] Clarification on ALPN support with JDK 8u261

For OpenJDK 8u262 you'll want the jetty-alpn-openjdk8-*.jar files

For Oracle 8u261 ... we don't know, as the code for 8u261 is not published or available.

You can use the jetty-alpn-agent which detects functionality of the running JVM and uses the appropriate alpn libs.

Trying to understand the ALPN related artifacts needed with JDK 8u261.

And would like to confirm, that with JDK 8u261:

1. Seems like alpn-boot.jar is not required at all: neither as Xbootclasspath parameter nor in classpath.
2. Seems like we only need jetty-alpn-openjdk8-client.jar in the classpath.
3. If point 2 above is correct, how does alpn-api.jar provided dependency come? The necessary support, previously, came from alpn-boot.jar. 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
How would we get this support/compatibility with alpn-boot.jar not in picture?

Would appreciate it if someone can confirm and clarify these points.
