> {{MetricRegistryMBean}} is not thread safe due to usage of {{histogramNames}} instance of {{HashMap}} class. Changing {{HashMap}} to {{ConcurrentHashMap}} will not help a lot (likely) because method {{MetricUtils.histogramBucketNames()}} uses just {{put}} method ({{putIfAbsent}} will help I believe).
> {{OpenCensusExporterSpi}}  uses the same {{MetricUtils.histogramBucketNames()}} method. But it isn't issue for this exporter because it is single threaded.
> Also {{MetricUtils.histogramBucketNames()}} method is responsible for histogram bucket's name representation. I believe that it is responsibility of metric exporter and this method should be removed from {{MetricUtils}}.
