It appears that if the commit fails, spring batch will get an OptimisticLockingFailureException when it tries to revert the changes to the step execution. In my particular case, I have a callback through EclipseLink to update history tables before a transaction is committed. If a failure occurs during this callback, the commit fails.
From looking through the code and the attached log file, the step execution is updated and committed before the main transaction is committed. When the commit fails, the old values for the step execution (including version) are updated to the values before the chuck started. When control returns to AbstractStep.execute(), the OptimisticLockingFailureException is thrown when the step execution is updated with the failed status because the new version had already been committed to the database.
