> Interns.java outputs "Metrics intern cache over flow" warn log for metrics
> info/tag when the cache reaches the hard-coded limit and the oldest cache is
> discarded for the first time. I'm thinking this log level can be changed to
> info because
> * there is no problem when the oldest cache is removed. if the metrics
> info/tag is not in the cache, simply create it.
> * we cannot configure the maximum size of the cache, so there is no way to
> stop the warn log.
