Yes, the reason I didn't use the "BATCH_" prefix was that the jobRepository is not involved directly on the BatchJobLocator tables. I was wondering if this config would have any impact if we prefix "BATCH_" on BatchJobLocator tables:

<batch:job-repository id="jobRepository"
			data-source="dataSource" transaction-manager="transactionManager"
			isolation-level-for-create="SERIALIZABLE" table-prefix="BATCH_" />
