Review comment:
If `refreshKrb5Config` is not set to true, whether `krb5.conf` is
always read or not when a new connection is established can depend on the
implementation for each JDBC driver.
We can remove the assertion because the remaining two assertions are
important.
The second assertion ensures that `refreshKrb5Config` enforces to refresh.
