Performance counters through MBeans doesn't work.

We are creating the InstrumentationManager according to documentation and this all works fine in CXF 2.7.12.

<import resource="classpath:META-INF/cxf/cxf.xml"/>
...
 
<bean id="org.apache.cxf.management.InstrumentationManager"
  class="org.apache.cxf.management.jmx.InstrumentationManagerImpl">
  <property name="enabled" value="true" />
  <property name="bus" ref="cxf" />
  <property name="usePlatformMBeanServer" value="true" />
</bean>

But after a little debugging, I noticed that in CXF 3.1.1 the 'register' method in InstrumentationManagerImp is deprecated and the code has been moved to the end of the 'init' method though there is a difference. CXF 2.7.12 had:

bus.setExtension(this, InstrumentationManager.class);

but CXF 3.1.1 has:

this.bus.setExtension(this, BusLifeCycleListener.class);

Could this be the cause that performance counters through MBeans aren't working. Or do we need to change the configuration?
