Description

I just discovered that a @HopMetadataProperty used with a double primitive type cannot be deserialized. I still don't understand why it works with int and boolean primitives but not with double?

 

To reproduce replace type int with double in test for field startYear in class org.apache.hop.metadata.serializer.json.occupation.Occupation and run tests.
