Elasticsearch Shield throws CreationException

Question

I'm trying to set up a running service which uses Elasticsearch with Shield. However when I try to start the service I get the following error:

org.springframework.beans.factory.BeanCreationException: 
Could not autowire field: private java.util.List com.company.AppConfig.identConfigs; 
nested exception is org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'demoident' defined in URL [file:C:/path/to/config/foo.xml]:

with key [TypedStringValue: value [default], target type [null]]; 
nested exception is org.springframework.beans.factory.BeanCreationException:

4 errors

(Sorry for the ugly formatting of stacktrace, feel free to edit for readability)

If I remove the Maven dependency for Elasticsearch Shield then the service starts as expected, without stacktraces, but obviously won't be able to execute any queries because of the exclusion of Shield.

Any help or input at all would be very appreciated.

Edit: I realized that the error is thrown by the Java client, not Elastic itself.
