This is a complicated one. First off: this handler should only be used for WorkingCopies (see EclipseSerializerRegisteringCopier)!

First case:
The user creates a SpringDataEclipseStoreLazy and puts a object in it. This object is stored as with a default BinaryTypeHandler. But when it gets loaded, it does not load as the stored object, but it gets wrapped in a Lazy.Reference(Object).

Second case:
The actual lazy object gets loaded from the actual storage. In this case the ObjectSwizzling is important! It's the actual ObjectSwizzling from the storage (not from the EclipseSerializerRegisteringCopier). This means, the SpringDataEclipseStoreLazy holds the objectId of the original lazy in the original storage. Therefore if Lazy.get() is called a new working copy of the lazy from the storage is loaded.
