com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of org.openapitools.jackson.nullable.JsonNullable (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator)

Since 0.17 topic objects with leaders are failing to unmarshal, the exception we are seeing is:

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `org.openapitools.jackson.nullable.JsonNullable` (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator)

Here's a simple test that reproduces the issue. The problem appears to be with the setter.

@k-wall Thank you for logging issue.
0.17.0 introduced number of breaking changes and we are in process of testing it against unreleased service version of service.

If problem occurs on production I recommend downgrading to 0.16.0 for now.

I will look to replicate this issue against stage API
to see if we need to do any fix on SDK.
