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

[Neha Munjal <neha.munjal3@xxxxxxxxx>]

Hi,

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

Have been going through this page: https://www.eclipse.org/jetty/documentation/current/alpn-chapter.html#alpn-openjdk8

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.

Thanks

Neha
