----------------------------------------

Thank you [~BilwaST] for patch.

# Move {{JvmMetrics.initSingleton}} to Router class.  
{code}
    DefaultMetricsSystem.initialize(METRICS_NAME);
    JvmMetrics jm = JvmMetrics.initSingleton("Router", null);
    pauseMonitor = new JvmPauseMonitor();
    addService(pauseMonitor);
    jm.setPauseMonitor(pauseMonitor);
{code}
# Handle check style issues
# Fix whitespace issues
# Testcase seems no correct. Checking service count seems appropriate.
