             Summary: NPE validating unbounded window functions
                 Key: CALCITE-1869
                 URL: https://issues.apache.org/jira/browse/CALCITE-1869
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Jess Balint
            Assignee: Julian Hyde
             Fix For: 1.14.0


If I create an OVER call with {{null}} bounds arguments, there's an NPE. We should add a null-check around these {{accept()}} calls.
