Springboot & Mockito - Using ReflectionTestUtils.setField calling method twice

I want to inject value to a private field annotated with @Value in my Junit5 unit test.

@Value("$(invoice.maxRetry)")
private maxRetry;

I referred this and used ReflectionTestUtils.setField which solved my problem by injecting a value but failed when verifying the no. of times the method get called.

MyClass:

    public class MessageProcessor {
         
    @Value("$(invoice.maxRetry)")
        private maxRetry;
    
    protected void handleMessage() {
            if(retry > maxRetry) {
                kafkaTemplate.sendMessage(msg);
       }
}

TestClass:

@ExtendWith(MockitoExtension.class)
public class MessageProcessorTest {

@Mock
private kafkaTemplate kafkaTemplate;

@Mock
private MessageProcessor messageProcessor

@Test
test() {
     ReflectionTestUtils.setField(messageProcessor, "maxRetry", "5");
     doNothing().when(kafkaTemplate).sendMessage(any());
     messageProcessor.handleMessage();
     verify(kafkaTemplate).sendMessage(any());
  }
}

Error running above test

org.mockito.exceptions.verification.TooManyActualInvocations: 
kafkaTemplate.sendMessage(<any>);
Wanted 1 time:
But was 2

I want kafkaTemplate.sendMessage(); to be called only once but getting called twice after adding ReflectionTestUtils.

Need advice on how to fix this.
