             Summary: NPE simplifying range expressions when literal value is null
                 Key: CALCITE-1982
                 URL: https://issues.apache.org/jira/browse/CALCITE-1982
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.14.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez
             Fix For: 1.14.0


The problem is that we do not check for {{null}} literal values before going into the method that tries to simplify the ranges.
