> ProxyOpComplete is not accurate in FederationRPCPerformanceMonitor when RemoteException
is returned.
> Because the remoteException is unwrap in invoke method, and it will be proxyOpComplete(false)
in invokeMethod.
> {code:java}
> // invoke method
> if (ioe instanceof RemoteException) {
>   RemoteException re = (RemoteException) ioe;
>   ioe = re.unwrapRemoteException();
>   ioe = getCleanException(ioe);
> }
> // invokeMethod method
> if (this.rpcMonitor != null) {
>   this.rpcMonitor.proxyOpFailureCommunicate();
>   this.rpcMonitor.proxyOpComplete(false);
> }
> throw ioe;{code}
