I am going to try to summarize it here. When batch mode is on, hibernate.jdbc.batch_size > 0. The update statement(s) that should increment the versioned column are not included in the committed batch. Then they are released after original batch is closed. I happened to find that question while trying to understand this message in my Spring Boot 3.1.1 project’s log HHH100503: On release of batch it still contained JDBC statements The above message shows up, since it is an INFO level but it doesn’t point to a cause or what was missing because of this. An aside, not knowing a lot about this error, is there a reason HHH100503 message is INFO and not WARN or even ERROR? Since data loss occurs it is hard to notice that this was part of the cause. I have ORMUnitTestCase that I am translating into a hibernate-orm/hibernate-core test PR and will update this as soon as I have it ready. The regression started between 6.1 and 6.2. With the current test case it is successful in 5.6.15.Final and 6.1.7.Final but fails on 6.2.0 and above including 6.2.6.Final, 6.2.7-SNAPSHOT and 6.3.0-SNAPSHOT. Once I increased the log level these two lines also show up in the debug/trace logs. Along with a lot of other ones I am not sure which ones will be useful. Log: {{Releasing statement [prep3: update HHH123_Calendar set version=? where id=? and version=? {1: 2, 2: CAST(1 AS BIGINT), 3: 1} ]}} HHH000420: Closing un-released batch PreparedStatementDetails did not contain PreparedStatement on #releaseStatements : update HHH123_Calendar set version=? where id=? and version=?
