    Description

      Support JDK 20.

      We currently support JDK (and OpenJDK) versions up to 18. (CALCITE-5747 will add support for JDK 19.) JDK 20 is the latest. We should support JDK 20 in Calcite 1.35 if possible, or soon after.

      This change would modify history.md (for the upcoming release), add JDK 20 to the GitHub CI, and fix the build. There are deprecation warnings (which we treat as errors) regarding the java.net.URL constructor.
