Although there's now a 'fix' in, it is only going to do automatically what
you are doing by hand.
My hunch is that perhaps the script, or env variable, already contains a
classpath with "0.9.0" jars in it, which means that when they're replaced with
differently-named jars, suddenly it can't find basic classes. Just a guess.
(Not sure what support will do with it given that this is into unsupported
territory. You can ask. There's a reasonable question here about understanding
the deployment. They'll reach out to the right people as needed.)
