Upstream doesn't test against OpenJDK, and they close bugs without
fixing them when it only affects OpenJDK and it isn't grave. I know this
from one of the upstream from Cassandra, who is also a Debian developer.
Because of this state of things, he gave up on packaging Cassandra in
Debian (and for other reasons too, like not having enough time to work
on the packaging).

I trust what this Debian developer told me. If I remember correctly,
it's Eric Evans <eevans at debian.org> (ie, the author of the ITP at
https://bugs.debian.org/585905) that I'm talking about.

A *hard* requirement, probably not. But this doesn't mean that Cassandra
works *well* on OpenJDK.

Anyway, I'd prefer if nobody trusted me, and that this was seriously

Ah! Thanks for finding out the details I was missing... :)
With this kinds of problems, I don't think anyone would like to take the
responsibility to upload Cassandra to either Debian or Ubuntu. At least
*I* wouldn't.

That being said, maybe the issue that Clint quoted is fixable. Probably
the issue is that nobody really cares... (yet?)
