> In ensureType() we don't correctly handle the case when nullability should be ignored. We still compare digests of the two types which returns false even when the types are the same but differ only in nullability. 
> Created a [Pull Request|https://github.com/apache/incubator-calcite/pull/97] with the description of the issue and a unit test.
