I believe a precedent for this must exist... when the Java 6 JRE was released, were users of the Java 5 JRE automatically updated to Java 6 JRE?

Or to put it another way, are automatic update capable of moving you from one major version to another (e.g. from JRE 5 --> JRE 6), or do they just update the "maintenance" releases within a version (e.g. JRE 1.6.0_25 --> 1.6.0_26)?

A similar question was asked on SO and told to move here! –  cagcowboy Aug 3 '11 at 10:27

It's absolutely fine to stay here. Java is something not only programmers have installed. –  slhck Aug 3 '11 at 10:29
    
@cagcowboy, thanks for finally getting some kind of answer to my question. Rather shocked that it was closed here too. –  smackfu Aug 3 '11 at 12:42

I think this depends on the OS. Microsoft can do it differently that Apple, and all of the different Linux distributions have their own policies. –  KeithB Aug 3 '11 at 14:33

No, the latter: If you had version 5, you had to download version 6 separately. At least in the past, it only updated maintenance releases. It is hard to say if version 6 will actually update to version 7 though since it has not happened yet.

I hate java updates period. –  surfasb Aug 3 '11 at 17:52
    
This is actually wrong. JRE 5 did update to JRE 6, although only a few updates in. Security updates are synchronised between releases. –  Tom Hawtin - tackline Oct 5 '11 at 22:05
