[GitHub] [pulsar] coderzc opened a new pull request, #16076: [fix][broker] Fix NPE when get /admin/v2/namespaces/public/default/maxTopicsPerNamespace
coderzc opened a new pull request, #16076:
URL: https://github.com/apache/pulsar/pull/16076
Fixes #16063
### Motivation
Server will throw a NPE when `max_topics_per_namespace == null`, because of the `internalGetMaxTopicsPerNamespace` return type is `int`.

Review Comment:
Looks like we can't return a null value to the admin client
admin/Namespaces.java
```java
int getMaxTopicsPerNamespace(String namespace) throws PulsarAdminException;
```
I think we can return 0 instead.
And please add UT for the new change.
