Windows server and Oracle Java updates

[Dave Bartholomew]

First, note that I'm using the EXE install program and not a zip file.

Because I avail myself of the option to change the destination directory
(so as to avoid your long list below...).

There are two JREs involved - one within the JDK (which comes along for
the ride and which I therefore install) and a separate JRE that hooks into
the browser than I decline to install (at least on a server). You'll find
the jre directory within any of your JDK directories below if you drill
down a bit. And I turn your jre1.8xxx directories below into just JRE for
the same reason (i.e. to lose the numbers and to be able to install in the
same place all the time), but only when installing Java on workstations.

Yes, I would do that too - if I were still running on Linux...

I do run the JDK.

Actually I now have different questions

Firstly, why does that work?  On my machine the JREs all go into version
depended directories:

Directory of C:\Program Files\Java

3/08/2014  14:31    <DIR>          jdk1.6.0_45
9/04/2014  15:25    <DIR>          jdk1.7.0_55
2/07/2014  09:36    <DIR>          jdk1.8.0_11
9/10/2016  13:32    <DIR>          jdk1.8.0_112
9/06/2016  14:04    <DIR>          jdk1.8.0_91
9/10/2016  13:32    <DIR>          jre1.8.0_112
1/10/2015  09:25    <DIR>          jre1.8.0_20
0/01/2016  14:08    <DIR>          jre1.8.0_65
4/04/2016  09:11    <DIR>          jre1.8.0_71
9/10/2016  13:30    <DIR>          jre1.8.0_91
3/08/2014  14:31    <DIR>          jre6
9/04/2014  15:25    <DIR>          jre7

But there isn't a 'jre' directory.  Is this something you maintain?  One
of the discussions we had was to expect people to maintain a symlinked
folder to the "latest" jre/jdk and use that explicitly.

Secondly have you noticed any problems with running the JRE rather than
the JDK, particularly the status page?  For historic reasons (to do with
JSPs not working) we recommend running the JDK  but if we could relax that
that would be good.
