that seem to point to Webcenter Content classes ie.

oracle/webcenter/content/integration/spi/ucm/UCMCacheHelper.cacheSecurityInfo(UCMCacheHelper.java)

oracle/webcenter/content/integration/spi/ucm/SecurityInfoHelper.cacheSecurityInfoFromDocumentDataObject(SecurityInfoHelper.java)
oracle/webcenter/content/integration/spi/ucm/SecurityInfoHelper.cacheSecurityInfoFromDocumentCollection(SecurityInfoHelper.java)
oracle/webcenter/content/integration/spi/ucm/SecurityInfoHelper.extractAndCacheSecurityInfoFromCollectionDisplayResponseBinder(SecurityInfoHelper.java)
oracle/webcenter/content/integration/spi/ucm/NodeOps.getCollectionDisplayDataBinder(NodeOps.java)

etc.
