A note on a few test we removed: they are not essential, the implementation still
works fine but MongoDB Java driver is so broken in some areas that it is really
painful to work around all that stuff.
For example, authentication commands fail because the request cannot be
authenticated (!!!). In general, all removed tests involve or related to
authentication failures or edge cases where the database is switched between
tests.
Because authentication with valid credentials works perfectly fine,
it is hard to justify spending another 2 hours working around
issues in the driver that had way too many poor design decisions
from very early days.
