Vladimir Sitnikov resolved CALCITE-4285.
----------------------------------------
Fix Version/s: 1.27.0
Resolution: Fixed
Fixed in
https://github.com/apache/calcite/commit/d9a81b88ad561e7e4cedae93e805e0d7a53a7f1a
Note: jsr305 is still available on the classpath since Guava still has jsr305
dependency. However, jsr305 must not be used in Calcite for both consistency
and type annotations reasons.
> Replace jsr305 dependency with checkerframework and errorprone_annotations

>
> jsr305 does not support type annotations, so it can't be used like
> {{List<@Nullable String>}}, and it results in duplicate {{@Nullable}}
> annotations on the classpath (checkerframework and jsr305)
> The solution is to use {{checkerframework}} for nullability, and
> {{errorprone}} annotations for dataflow-like checks (e.g.
> {{@CheckReturnValue}})
