Major I created a content type with a mandatory long metadata.
Trying to save a content of this type fails, triggers an error. The stacktrace is:
[J cannot be cast to [Ljava.lang.Object;
java.lang.ClassCastException: [J cannot be cast to [Ljava.lang.Object;

[...]
It appears to be because the EditContentFunction creates a long[], and DefaultValidator only handles scalar values or Object[], and tries to cast long[] to Object[].
The problem may present itself with double and boolean metadata (even if a mandatory boolean metadata isn't the most logical thing in the world).
