Oh, I misunderstood -- you're not trying to bootstrap, but getting
this error anyway.

I'd probably call this "wontfix" for 0.4 since the fix is basically
all the work on ReplicationStrategy that's been done for 0.5, which
shouldn't be backported to a stable release imo.  The silver lining is
that 0.5 will be out soon.

If you want a workaround in the meantime, make
getWriteStorageEndPoints just return getReadStorageEndPoints(token)
which will not treat bootstrap nodes correctly but it should work fine
otherwise. :)
