My organization uses a necessary Java-based web app that will not be replaced in the near future, which runs on Java 1.4 and up. Should our (mostly Windows) users have Java 1.6, 1.7, or a different version on their PCs? Does the answer vary across OS versions, browsers, or other variables? Should they allow auto-updating?

If the workstations are connected to the interent you should push any and all updates and use the current version of Java otherwise you will be vulernable to malware. –  Ramhound Dec 6 '12 at 16:15

@RedGrittyBrick - Which is the reason only the "current version" is the only correct answer. –  Ramhound Dec 6 '12 at 16:41

the only reasonable answer to this question is "the most up-to-date one". always being up to date reduces the number of known exploits to its theoretical minimum.

+1, but this doesn't tell quite the whole story. Java 6, for example, is still maintained alongside Java 7 (at least for the moment), and therefore there are two different versions that can both be called "up-to-date". –  Joel Coehoorn Dec 6 '12 at 16:44
    
be ready to update your JVM several times per month, to stay up-to-date with the very frequent security patches. –  BorisHajduk Dec 6 '12 at 17:56

Safe solution would be, using separate browser with java plugin, restricted only to your webapp. And other one for accessing internet.
