Review Comment:
After this change, the `cacheEvictionTask` method is never used anymore, we
should remove it.

Review Comment:
I think this config should be removed rather than deprecated. Because it's
never used and this config cannot be configured directly by user.
If you have concern about the usage from other library, I think you can add
a getter like:
```java
@Deprecated
private double cacheEvictionFrequency = 0;
public long getCacheEvictionIntervalMs() {
return (cacheEvictionFrequency <= 0) ? cacheEvictionIntervalMs : /*
... */;
}
```
