Roman Khachatryan created FLINK-26092:
-----------------------------------------
Summary: JsonAggregationFunctionsITCase fails with NPE when using
RocksDB
Key: FLINK-26092
URL: https://issues.apache.org/jira/browse/FLINK-26092
Project: Flink
Issue Type: Bug
Components: Runtime / State Backends, Tests
Affects Versions: 1.14.3, 1.15.0
Reporter: Roman Khachatryan
Assignee: Roman Khachatryan
Whith RocksDB backend chosen manually (instead of Heap; e.g. by altering
mini-cluster configuration in BuiltInAggregateFunctionTestBase);
the test fails with NPE.
Not sure whether it's a RocksDB issue, a test issue, or not an issue at all.
The current Changelog backend behavior mimics RocksDB, and therefore enabling
it with materialization fails the test too (Changelog + Heap).
