OSB JMS Reporting Provider miserably failing when non-Gridlink Datasource used for wlsbjmsrpDataSource

The error we find in the logs , whenever we try to access the OSB Message Reports in Operations, is:

<BEA-494002> <Internal error occured in OSBConsole : null
java.lang.RuntimeException
at com.bea.wli.reporting.jmsprovider.runtime.ReportingDataAccessImpl.getDBCurrentTS(ReportingDataAccessImpl.java:490)
at com.bea.alsb.console.oam.reporting.jmsprovider.ReportingHelper.getCurrentDBTS(ReportingHelper.java:293)

at com.bea.alsb.console.reporting.jmsprovider.ReportManagementFlow.viewMessages(ReportManagementFlow.java:85)

Since we use RAC, we should transform the wlsbjmsrpDataSource into a GridLink DS.
