Oh, and C* is definitely *not* designed to be in-memory restartable. There are
many singletons that would preserve state between restarts, {{Schema}} being
just one of the many. I'm actually not sure that a patch for just this ticket
would really help you, and not just hide one symptom of larger problems in the
system. What I can do is provide a slightly better custom patch, but that logic
wouldn't make much sense to someone - and that change alone will most
definitely not make CassandraDaemon restartable, unfortunately. That would
require a lot more effort.

Thanks for the stack trace. You almost guessed the issue, but not quite. It's
just that old schema tables (system.schema_*) are unloaded from memory by then.
The easiest fix would be to check if system.schema_* tables are in {{Schema}}
and not attempt if they aren't.
None of it is a problem for Cassandra-proper, it really works as it's designed
to. C* is not *really* built for being embeddable, so there have to be many
issues like that in embedded mode. That said, I can put in an easy fix for just
this one problem (but you'll have to test the patch).
