--------------------------------

{{865000096028875386}} is the {{serialVersionUID}} from the source, I have no idea where the persister got the {{-5383960985588784105}} version from.

> The field and method metadata classes have a {{serialVersionUUID}}, but {{ComponentMetadata}} itself doesn't have it, so it can change at any time.
