> ContainerMetrics is able to unregister itself during the getMetrics method,
> but that method can be called by MetricsSystemImpl.sampleMetrics which is
> trying to iterate the sources. This leads to a
> ConcurrentModificationException log like this:
> {noformat}

> impl.MetricsSystemImpl: java.util.ConcurrentModificationException
