BatchingBatch will log failed executions at an "ERROR" level with the SQL values included. This could compromise security or violate compliance by including secrets or personal information in the logs, but squelching all ERROR level logs for the class is not desirable.
Since this exception is logged and then a new exception re-thrown, it should be logged at a DEBUG level, and the handler of the exception should be tasked with log the exception. That also would allow the exception to avoid being logged twice or logging it as an ERROR in a non-fault use case, e.g. optimistic de-duplication of data.
At the very least, it should not be logged with the values at an ERROR level.
