Swagger SpringMVC Integration (Failed to load @PostConstruct method)

I am trying to integrate swagger-springmvc 0.9.5 with SpringMVC 3.2 project with XML configuration.

My app-config.xml:

<beans xmlns="ht...

<context:annotation-config />
<mvc:annotation-driven>
    <mvc:message-converters>
        <bean id="messageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" />
    </mvc:message-converters>
</mvc:annotation-driven>


<context:component-scan base-package="com.myapp.info.v1.rest.endpoint"/>
<bean class="com.mangofactory.swagger.configuration.SpringSwaggerConfig" />

</beans>

I get the following error:

java.lang.NullPointerException
com.mangofactory.swagger.models.property.field.FieldModelPropertyProvider.propertiesForSerialization(FieldModelPropertyProvider.java:54)
com.mangofactory.swagger.models.property.provider.DefaultModelPropertiesProvider.propertiesForSerialization(DefaultModelPropertiesProvider.java:31)

com.mangofactory.swagger.core.SwaggerApiResourceListing.initialize(SwaggerApiResourceListing.java:72)
com.mangofactory.swagger.plugin.SwaggerSpringMvcPlugin.initialize(SwaggerSpringMvcPlugin.java:427)
...

I started to debug, and realized the following:

1. objectMapper is null


2. setObjectMapper is never called


3. setup() is never called, although it has @PostConstruct annotation.

I found three posts with the same error but none of them seem relevant. Am I forgetting something? I am new to SpringMVC framework.

Sidenote: I also experimented with swagger-springmvc 0.6.6 and managed to get it work.
