does anyone know why gradle would fail to run tests that succeed with maven?

I have a test that calls out to a common company jar to instantiate a `Jackson2JsonMessageConverter`

```
    @Bean(name = "jackson2jsonMessageConverter")
    public MessageConverter jackson2JsonMessageConverter(@Qualifier("amqpObjectMapper") ObjectMapper objectMapper) {
        return new Jackson2JsonMessageConverter(objectMapper);
    }
```

Now when I call out to this java library from a kotlin test in a gradle project (converting from maven) I get this error

```
java.lang.NoSuchMethodError: org.springframework.amqp.support.converter.Jackson2JsonMessageConverter.&lt;init&gt;(Lcom/fasterxml/jackson/databind/ObjectMapper;)V
```

but if I just call out to `new Jackson2JsonMessageConverter(objectMapper)` manually I get no error and the tests succeed!
