Json type doesn't supports generic type

@Type(type = "json") @Column(columnDefinition = "json") private Location location;
works fine.
@Type(type = "json") @Column(columnDefinition = "json") private List<Location> locations; will failed.
( (ParameterType) parameters.get( PARAMETER_TYPE ) ).getReturnedClass() should return ParameterizedType instead of Class.
Maybe AttributeConverter is a better solution.

It's intended to be like that because PostgreSQL and MySQL allow you to save a single root JSON object. Mapping a list of JSON objects is not, therefore, supported.
