[jira] [Created] (FLINK-16181) IfCallGen will throw NPE for primitive types in blink

Benchao Li created FLINK-16181:
----------------------------------

             Summary: IfCallGen will throw NPE for primitive types in blink
                 Key: FLINK-16181
                 URL: https://issues.apache.org/jira/browse/FLINK-16181
             Project: Flink
          Issue Type: Bug
            Reporter: Benchao Li


It can be reproduced by a simple test case:

Add below to {{ScalarOperatorsTest}}
{code:java}
testSqlApi("IF(true, CAST('non-numeric' AS BIGINT), 0)", "null")
{code}
 

IMO, it's {{IfCallGen}}'s bug, which should judge the nullTerm of operands first before assignment.
