Track if we missed running integration tests with plugins on Java 1.8. It looks a problem with notebooks plugin.

[joshuali925]

notebooks is merged into observability, but I'm able to confirm the issue on 1.2 observability. We will look into this, as a workaround could you try running it with JAVA_HOME= ./bin/opensearch? This worked for me as it's going to use the JDK bundled in OpenSearch, which is JDK 15

[anirudha]

https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/file/Path.html#of(java.lang.String,java.lang.String...)

is only available in java 11 onwards which is used by many plugins

[anirudha]

opensearch-project/opensearch-plugins#64
pending for java 8 support on plugins

[jcgraybill]

Looks like affected plugins are reports-scheduler, notebooks, observability - from that list above. (Everything else is test, unreleased, or data-prepper.) Pls create issues and fix in all three for the 1.3 release.

[saratvemulapalli]

@joshuali925 / @anirudha I see notebooks plugin is already being built for 1.8. But we are using it with JDK 14.
Ref: https://github.com/opensearch-project/notifications/blob/main/notifications/build.gradle#L78
(I couldn't find a repo for observability)

Integration tests are being run with JDK 14.
Ref: https://github.com/opensearch-project/notifications/blob/main/.github/workflows/notifications-test-and-build-workflow.yml#L38

Yeah looks like even though plugins are being built for JDK 8/ Java version string 1.8, we are only testing it in JDK 14 or the bundled JDK with OpenSearch.

As @anirudha said opensearch-project/opensearch-plugins#64 should be completed before we can support them.

Let's sort this all out for 1.3, starting with opensearch-project/opensearch-plugins#64 across all plugins.

OpenSearch 1.3.0 has restored JDK8 support via opensearch-project/opensearch-plugins#64. Please reopen if you're still seeing problems on JDK8. Note that in 2.0 support for JDK8 will be removed.
