  * @brief This class allows loading and unloading of dynamically linked libraries which contain class
  * definitions from which objects can be created/destroyed during runtime (i.e. class_loader).
  * Libraries loaded by a ClassLoader are only accessible within scope of that ClassLoader object.
+ * This class inherit from enable_shared_from_this which means we must used smart pointers,
+ * otherwise the code might work but it may run into a leak.
