I can't find the reference to it, but I seem to remember encountering a
bug back in November involving either nested variable expansion or
variable expansion not happening in certain contexts.

That said, I just ran an experiment with 1.3.1 using:
| <package
|     id="jre8"
|     name="Java Runtime Environment 8"
|     revision="%version%"
|     reboot="false"
|     priority="20">
|     <variable name="shortupdatever" value="45" />
|     <variable name="version" value="8.0.%shortupdatever%" />

and it read the version number correctly, trying to upgrade when the
local machine had 44 and downgrade when it had 46, so there must be
something else at work.

Not the same one as you're using, but the package that uses PowerShell
to do its dirty work:


is loosely based on it and is what I use in my environment. No Java
updates have come out since I put it into production, but it handled the
upgrade to 8u45 cleanly in my test environment.

On a related note, if anyone's using my unpack-core.zip hack to deal
with broken Java installations, I discovered it wasn't working (when I
investigated a machine where JRE 7u79 wouldn't uninstall) and put a fix
on the wiki on Wednesday.
