AEM 6.0 Capacity Guide Benchmark Scenarios?

    Adobe has published a capacity guide based on performance tests that were conducted in their labs as indicated below. Is this the right capacity guide for AEM 6.0 because they are using JDK 1.6. I thought the recommended JDK was 1.7. Can someone clarify if this is the right documentation
