BeanTypeRegistry getConfigurationClassFactoryBeanGeneric only considers @Bean methods that take no arguments

[wilkinsona]

For example, this @Bean method won't be found:

@Bean
public EmbeddedSolrServerFactoryBean solrServer(
        @Value("solr.solr.home") String solrHome) throws Exception {
    EmbeddedSolrServerFactoryBean factory = new EmbeddedSolrServerFactoryBean();
    return factory;
}

This means that the type of the solrServer bean is unknown and SolrAutoConfiguration ends up overriding it as the evaluation of @ConditionalOnMissingBean doesn't find the existing bean.
