Spring #EnableCaching with #Inject/#Autowired issue - spring

Question

I found an issue when using #EnableCaching annotation together with #Inject/#Autowired in #Configuration class:
Simple example to reproduce:
Configuration class:
#Configuration
#EnableCaching
public class CacheConfig {
#Inject
private DataSource dataSource;
#Bean
public CacheManager cacheManager(){
SimpleCacheManager cacheManager = new SimpleCacheManager();
cacheManager.setCaches(Arrays.asList(new ConcurrentMapCache("books")));
return cacheManager;
}
#Configuration
static class DevProfileConfig {
#Bean(destroyMethod = "shutdown")
public DataSource dataSource() {
EmbeddedDatabaseFactory factory = new EmbeddedDatabaseFactory();
factory.setDatabaseType(EmbeddedDatabaseType.HSQL);
return factory.getDatabase();
}
}
}
Application context launcher:
public class CacheConfigLauncher {
public static void main(String args[]){
ApplicationContext springAppContext = new AnnotationConfigApplicationContext(CacheConfig.class);
}
}
Error:
Caused by:
org.springframework.beans.factory.BeanDefinitionStoreException:

spring.samples.config.CacheConfig.cacheManager()] threw exception;

However if you comment out either #Inject'ed field or #EnableCaching annotation configuration will be bootstraped without errors!!!
It seams like a bug for me. Have someone faced the same issue or probably I'm missing smth?
Thank you,
Oleg
