Benchao Li commented on CALCITE-5095:
-------------------------------------

PR for Calcite is ready: [https://github.com/apache/calcite/pull/2773]

However, Avatica has some problems after upgrading gradle/jdk/guava version, and it will take me longer to fire the PR.

> Java 18 is released as of 2022-03-22. Calcite should support it at compile time and run time.
> We should fix before Calcite release 1.31. To fix this, add JDK 18 to the CI targets in {{.github/workflows/main.yml}} and fix any errors/warnings. Modify {{site/_docs/howto.md}} and {{{}site/_docs/history.md{}}}.
> We should also fix before Avatica release 1.21. Let's use the same JIRA case for Avatica. To fix in Avatica, there will be similar changes to similar files.
> There is a new version of Guava (Calcite's current version is 30.0.1-jre, new version is 31.1-jre). It makes sense to upgrade Guava at the same time. IIRC you need to change {{{}main.yml{}}}, {{{}history.md{}}}, {{{}gradle.properties{}}}.
