> {{/jmx}} servlet responses invalid JSON, if some metrics are NaN:
> {code}
> "l1CacheHitCount" : 0,
> "l1CacheMissCount" : 0,
> "l1CacheHitRatio" : NaN,
> "l1CacheMissRatio" : NaN,
> "l2CacheHitCount" : 0,
> "l2CacheMissCount" : 0,
> "l2CacheHitRatio" : 0.0,
> "l2CacheMissRatio" : 0.0,
> {code}
> NaN is an invalid character sequence in JSON. We should not response NaN in
> metrics.
