[~danny0405], I see you added tests in CALCITE-3719 that use log4j Logger and Appender. Could these be switched to another logging framework?

> JDK 15 is now GA (released 2020/09/15). We should support it (and OpenJDK 15) as a build- and run-time platform.
> Also:
> * Upgrade to latest Guava (guava-29.0-jre, released on 2020/04/13);
> * Upgrade log4j2 to latest (2.13.3, release 2020/05/10);
> * Remove log4j (we're on the last release, 1.2.17, which was 2012/05/26, but I assume the project is now unsupported and dead).
> If there are any other important upgrades to be done before 1.26, please add them here.
> Must fix in next release (1.26) or justify why not in this thread.
