             Summary: RexSimplify incorrectly simplifies IS_FALSE(x) when x is 
nullable
                 Key: CALCITE-7619
                 URL: https://issues.apache.org/jira/browse/CALCITE-7619
             Project: Calcite
          Issue Type: Bug

    Affects Versions: 1.42.0
            Reporter: Mihai Budiu
             Fix For: 1.43.0


The expression is reduced to CAST(NOT(x) AS BOOLEAN NOT NULL). This is wrong 
when x is NULL.
