Review Comment:
FYI, I see for some other property, like `METADATA_PREVIOUS_VERSIONS_MAX`,
will be adjust to a normal value when it's less than or equal to 0,
```
int maxSize =
Math.max(
1,
PropertyUtil.propertyAsInt(
properties,
TableProperties.METADATA_PREVIOUS_VERSIONS_MAX,
TableProperties.METADATA_PREVIOUS_VERSIONS_MAX_DEFAULT));
```
