positive.code: [[MetricsComponent-registry]]Metric Registry
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  
  Camel Metrics Component uses by default `MetricRegistry` with
  `Slf4jReporter` and 60 second reporting interval. Default registry can
  be replaced with custom one by providing bean with name `metricRegistry`
  in Camel registry. For example using Spring Java Configuration.
  
negative.code: ----
  
  CAUTION: `MetricRegistry` uses internal thread(s) for reporting. There is no
  public API in version `3.0.1` for users to clean up on exit. Thus using
  Camel Metrics Component leads to Java classloader leak and my cause
  `OutOfMemoryErrors` in some cases.
