Sean Mackrory reopened BIGTOP-1589:
-----------------------------------
So I found some issues the other day - you need a correct combination of
ordering between the different regexes and between different matches of the
regexes, etc. and I just don't think you can get the wildcards to be evaluated
at only the right time. So I'm attaching a second attempt. I've tested it with
multiple versions of Oracle JDK 1.7 and multiple major versions of OpenJDK
installed and this finally got all of them in the right order at once.
Given how sensitive this is to any kind of gap in testing, I think it'd be
great to actually have this tried out by more people with various JDKs on
various distros before we try changing this again, rather than just a +1.

> bigtop-detect-javahome uses 'ls -rd' to sort the JDKs in each category in
> reverse lexicographical order, but I believe when we switched to having
> separate variables defined for each major JDK version we overrode that
> mechanism so older JDKs still take precedence over newer ones.
