===========
[2016-05-25 15:45:56,120] WARN Error processing kafka.server:type=FetcherStats,name=RequestsPerSec,clientId=console-consumer-25184,brokerHost=fe80::92e2:baff:fe92:62f,brokerPort=3392 (com.yammer.metrics.reporting.JmxReporter)

==============================
In the AbstractFetcherThread.scala line 264:
class FetcherStats(metricId: ClientIdAndBroker) extends KafkaMetricsGroup {
val tags = Map("clientId" -> metricId.clientId,
"brokerHost" -> metricId.brokerHost,
"brokerPort" -> metricId.brokerPort.toString)

When brokerHost is IPv6, the address has :, which can't use as ObjectName.
