------------------------------------
Summary: NPE exception on null array when indexing in Codegen
Key: SPARK-55747
URL: https://issues.apache.org/jira/browse/SPARK-55747
Project: Spark
Issue Type: Task
Components: Spark Core
Affects Versions: 4.1.1
Reporter: Stevo Mitric
GetArrayItem.nullable was incorrectly computed as false when the array type has
containsNull=false (e.g., from StringSplit) but the array itself can be null.
This caused codegen to skip null checks, leading to NPE when calling
array.numElements() on a null array during bounds checking.
