------------------------------------
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.
