how to assert orders of calls to one single mock?

I want to write a junit test with mockito

say this is my mock:

IServerApi routingServerApi = mock(ServerApi.class);
        when(routingServerApi.sendRequest(anyString(), eq("request1"))).thenReturn(myObj1);
        when(routingServerApi.sendRequest(anyString(), eq("request2"))).thenReturn(myObj2);

I want to verify that sendRequest is called with request1 just before it's called with request2 (and no other invocation between them).

How can i do this?

I have seen this SOF question,

but I want to verify order of calls to just one mock, not two.

This syntax doesn't work for me (compilation error when initing inOrder())

InOrder inOrder = inOrder(mockRoutingServerApi);

inOrder.verify(mockRoutingServerApi).sendRtUpdates(time1, ImmutableList.of("update1"));
inOrder.verify(mockRoutingServerApi).sendRoutingRequest("request1");
inOrder.verify(mockRoutingServerApi).sendRtUpdates(time1, ImmutableList.of("update2"));
inOrder.verify(mockRoutingServerApi).sendRoutingRequest("request2");

Some commented I can use ArgumentCaptor but I couldn't see how.
