Returning object of type specified in method arguments instead of AnyRef

I have the following method:

@org.springframework.stereotype.Service
class EntityCacheManager {
  def get(cacheId: String, entityClass: Class[_]): AnyRef = { ... }
  //...
}

So to use it, i have to write this:

val cachedEntity = entityCacheManager.get(cacheId, classOf[SomeEntity]).asInstanceOf[SomeEntity]

Is there some way to make EntityCacheManager.get() returning instance of type entityClass which is specified in method params? I'd like to avoid casting asInstanceOf every time i use this method. I know it would be nice to use generic definition of type EntityCacheManager, but it's also a spring-managed bean, so i think using generics will cause troubles.
