Jonathan, Pulsar 2.8 (and 2.9) builds well on JDK8 and JDK11. Tests are passing. Developers can use both JDK8 and JDK11. CI is running ONLY on JDK11 and we have a single workflow that runs some tests on JDK8. The binary tarballs work with JDK8 and JDK11 The Java client works with JDK8 and JDK11
The docker images are based on JDK11, so all the k8s users that use ASF Pulsar Docker images run on JDK11 We should ensure that Pulsar runs and builds well on JDK17 but currently there is no ongoing effort in the community Cheers Enrico Il giorno mar 31 ago 2021 alle ore 15:22 Jonathan Ellis <jbel...@gmail.com> ha scritto: > What is the plan to fully move to JDK 11 (or JDK 17 which will be released > as LTS in two weeks)? > > I remember Enrico starting a thread in February but I haven't seen an > update since then. > > On Tue, Aug 31, 2021 at 5:15 AM Hang Chen <chenh...@apache.org> wrote: > > > Hello Apache Pulsar Community, > > In Apache Pulsar 2.8.1 RC1, Enrico found "check-binary-license" > script > > fails on the staged tarball > > ``` > > ~/dev/pulsar/src/check-binary-license apache-pulsar-2.8.1-bin.tar.gz > > jetty-alpn-openjdk8-client-9.4.42.v20210604.jar unaccounted for in > > lib/presto/LICENSE > > jetty-alpn-java-client-9.4.42.v20210604.jar mentioned in > > lib/presto/LICENSE, but not bundled > > ``` > > > > After work with Enrico, he found jetty dependency > > http2-http-client-transport adds transitive dependencies depending on the > > JDK version > > > > > https://repo1.maven.org/maven2/org/eclipse/jetty/http2/http2-http-client-transport/9.4.42.v20210604/http2-http-client-transport-9.4.42.v20210604.pom > > > > with jdk8: > > > > mvn dependency:tree > > [INFO] | +- io.airlift:http-client:jar:0.195:compile > > [INFO] | | +- > org.eclipse.jetty:jetty-client:jar:9.4.42.v20210604:compile > > [INFO] | | +- > > org.eclipse.jetty.http2:http2-client:jar:9.4.42.v20210604:compile > > [INFO] | | | \- > > org.eclipse.jetty:jetty-alpn-client:jar:9.4.42.v20210604:compile > > [INFO] | | +- > > > > > org.eclipse.jetty.http2:http2-http-client-transport:jar:9.4.42.v20210604:compile > > [INFO] | | | \- > > org.eclipse.jetty:jetty-alpn-openjdk8-client:jar:9.4.42.v20210604:compile > > [INFO] | | \- net.jodah:failsafe:jar:2.0.1:compile > > > > with jdk11: > > > > [INFO] | +- io.airlift:http-client:jar:0.195:compile > > [INFO] | | +- > org.eclipse.jetty:jetty-client:jar:9.4.42.v20210604:compile > > [INFO] | | +- > > org.eclipse.jetty.http2:http2-client:jar:9.4.42.v20210604:compile > > [INFO] | | | \- > > org.eclipse.jetty:jetty-alpn-client:jar:9.4.42.v20210604:compile > > [INFO] | | +- > > > > > org.eclipse.jetty.http2:http2-http-client-transport:jar:9.4.42.v20210604:compile > > [INFO] | | | \- > > org.eclipse.jetty:jetty-alpn-java-client:jar:9.4.42.v20210604:compile > > > > In order to solve this issue, I will use JDK11 to release Apache Pulsar > > 2.8.1 instead of JDK8.
