docs: <p>
  Initializes a loaded type. This method must only be invoked via the system class loader.
  </p>
  <p>
  <b>Important</b>: This method must never be called directly but only by using a {@link NexusAccessor.InitializationAppender} which enforces to
  access this class for the system class loader to assure a VM global singleton. This avoids a duplication of the class if this nexus is loaded
  by different class loaders. For this reason, the last parameter must not use a Byte Buddy specific type as those types can be loaded by
  different class loaders, too. Any access of the instance is done using Java reflection instead.

  @param type           The loaded type to initialize.
  @param identification An identification for the initializer to run.
  @throws Exception If an exception occurs.
