Oh yes, this test mentions `rmid`, but it is basically a direct test of the `ReliableLog` stuff and it doesn't actually use or depend on Activation or `rmid`. The test still runs and passes.

I'll do a followup pass to see if anything in the system uses anything in the `sun.rmi.log` package. Maybe the only user was Activation.
