Exception in obtaining the client through username and password

__Steps to reproduce:__
List the minimal actions needed to reproduce the behavior.

```java
InfluxDBClientOptions.Builder builder = InfluxDBClientOptions.builder();
builder.bucket(bucket);
builder.org(org);
builder.okHttpClient(builder());
builder.authenticate(username, password.toCharArray());
builder.url(uri);
InfluxDBClientImpl client = (InfluxDBClientImpl) InfluxDBClientFactory.create(builder.build());
InfluxDBClientReactiveImpl reactive = (InfluxDBClientReactiveImpl) InfluxDBClientReactiveFactory.create(builder.build());
```

__Expected behavior:__
Describe what you expected to happen.

__Actual behavior:__
Describe What actually happened.

__Specifications:__
- Client Version:
- InfluxDB Version:
- JDK Version:
- Platform:

Start with InfluxDBClientOptions.Builder.authenticate and the InfluxDBClientFactory.create and InfluxDBClientReactiveFactory.create calls shown in the report. Reproduce the exception after filling in the missing client, server, JDK, platform, and expected-versus-actual behavior details. Done means the username/password client creation behavior is understood and the reported exception no longer occurs.
