fmiguelez opened a new issue #7046:
URL: https://github.com/apache/pulsar/issues/7046
If we try to create a consumer with `SubscriptionMode.NonDurable` it will
fail with a `NullPointerException`.
We try to mimic the behaviour of Reader with partitioned topics.
It can be reproduced this way:
```
final Consumer<T> consumer =
client.newConsumer(schema).topic(topicUri)
.readCompacted(true)
.subscriptionMode(SubscriptionMode.NonDurable)
.subscriptionType(SubscriptionType.Exclusive)
.subscriptionName(subscription)
.subscriptionInitialPosition(SubscriptionInitialPosition.Earliest)
.subscribe();
```
The exception throw is the following:
```
