When batching is turned on for entities that update multiple tables when updated following warn is logged: HHH100001: JDBC driver did not return the expected number of row counts Problem is in org.hibernate.engine.jdbc.batch.internal.BatchImpl.checkRowCounts when determining expectedNumberOfCounts. In case when we are updating one entity (which will set batchPosition to 1 ) which for example extends entity with inheritance strategy set to InheritanceType.JOINED , thus creating two update statements to be executed in DB, expectedNumberOfCounts will be wrongfully determined to be 0 (1/2) and warning will be logged. This seems to be a bug. Also in {{org.hibernate.engine.jdbc.batch.internal.BatchImpl.checkRowCounts }} when logging warning expected and actual are switched. |
