Base class not included in schema 'oneOf'

[big-andy-coates]

Given:

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME)
class BaseType {}
class SubType1 extends BaseType {}
class SubType2 extends BaseType {}

generator.registerSubTypes(List.of(BaseType.class));

When the schema is generated for BaseType it will only include the two subtypes in the oneOf clause. As BaseType is a non-abstract class it should also be included in the list.

This looks to be a bug in mbknor-jackson-jsonschema but needs investigating.
