Duplicate delete markers are not created on MinIO buckets with versioning, if an application performs a soft delete on an object repeatedly - that object will only ever have a single DELETE marker for all such successive attempts. This is done to ensure that repeated soft deletes do not ever need multiple versions in the first place.

> NOTE: Server side replication is supported for idempotent versions on delete marked objects.

### Motivation

                    ntHash = auth.getUnicodeHash(session.transport.server.encryptionKey);
                    // prohibit HTTP auth attempts for the null session
                    if (lmHash.length == 0 && ntHash.length == 0) {
                        throw new RuntimeException("Null setup prohibited.");
                    }

        Subject first = auth.getSubject();

        // Second call should return cached value (same as first)
        Subject second = auth.getSubject();

   * attempt to cancel itself.
