Yes, and they generally specify which jvm you need to use for the
application. That means pragmatically that an OS should be designed to
easily accommodate whatever jvms your apps need, concurrently if
desired. In the future I don't expect this to completely go away any
more than the existence of gcc made C compiler version dependencies go
away - but you will look at it differently when it's 'your' jvm versions
that are problematic.

But it doesn't stop there - farther down:
"For some reason I got an error in Statsd.

This could be an OpenJDK issue or just a testing issue, so I disabled
that daemon for now"

But not actually working like it is supposed to or in a usable way.

I think you are missing the pragmatic point again. I'm willing to
sometimes make some effort at beta testing but there are limits. And
right now one of those would be using a system that installs with no
extra work under vmware. If you can't respond to that or have the
answer in an official FAQ, I'll just wait until I have a specific need
for a feature I can't get elsewhere before trying to deal with it.
I don't really see the point of running an OS that is antagonistic
toward the drivers and applications that would make it useful but I'm
curious enough about how it is going to mesh with the next RHEL cut to
keep watching. By the way, shouldn't that cut have happened by now?
