With the latest serious Java vulnerability and Oracle operating on a three month patch window (in this case putting it some time in October) without much indication of breaking it the advice coming down is to disable Java (or at least the web JRE)- http://www.theregister.co.uk/2012/08/27/disable_java_to_block_exploit/ although said article notes for proper sysadmins there is a third party patch available. Personally I never noticed Java existing and then uninstalled it as a test some time back. Since then I have not noted anything really broken but it seems I have a bank with maybe a fraction of a clue about website building and the UK government seems just about able to handle CSS so no danger of java there any time soon (the less said about US government websites the better). On the client front I never install it as standard and do not even tend to carry around a standalone installer and what little corporate stuff I deal with does not want it either. Prediction of several replies- "I would but minecraft" Short version Java- still got it installed? If it is installed is it a vital piece of kit or something you have to work around?
