I think there can be thousands of reasons people wouldn’t be able to install Java 7 (including the fact that their admin operation team doesn’t want to use it, that it doesn’t work on such OS and such version, etc). I’d say that it should be in the documentation of Java 7 or the document of RHEL instead ;) I’m 100% against putting that information somewhere if you think it’s useful but I wouldn’t put it directly in the Prerequisites section at http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HPrerequis… since it can quickly becoming large and with little interest for 99% of people. What we did, was to have specific installation sections for Servlet Containers and for Databases since they require specific knowledges for XWiki. We could imagine doing that for OSes but I’m not sure what we would put in there, since we don’t have that much information and by large the OS should have nothing to do with XWiki since XWiki runs on Java and the JVM isolates from the underlying OS. I think that personally I wouldn’t put that information, similar that I wouldn’t put information about how Servlet Containers work because that information goes beyond XWiki. Requiring Java7 should be enough I think. WDYT? Thanks -Vincent
