SpringDataRestConfiguration ModelAttributeParameterExpander StackOverflowError

Hey,

I’m using the 2.6.0 release with spring-data-rest support (#699). I’ve already used springfox 2.5.0, no probs, everything working fine.

Im enabling the data-rest configuration using

@Import(SpringDataRestConfiguration.class)

During spring boot app startup i get:

Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

I am using 2.7.0 version, its working fine for me.

POM:

<dependency>
	    <groupId>io.springfox</groupId>
	    <artifactId>springfox-swagger2</artifactId>
	    <version>2.7.0</version>
	    <scope>compile</scope>
	</dependency>
	<dependency>
	    <groupId>io.springfox</groupId>
	    <artifactId>springfox-swagger-ui</artifactId>
	    <version>2.7.0</version>
	    <scope>compile</scope>
	</dependency> 
	
	 <!-- swagger implementations End -->

use this in controller

public Docket applicationApis() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select().apis(RequestHandlerSelectors.basePackage("com.test.um"))
                .paths(PathSelectors.ant("/um.*")).build();
	}

That works like a charm. Googled but no avail for days. Thank you very much for that.
