[QUESTION][JAVA] How to generate inner static class by spec?

[romanov93]

I use jaxrs-cxf generator

    AAA:
      properties:
        someValue:
          type: string
    BBB:
      properties:
        someValue:
          type: string

Is it possible to make BBB is inner class into AAA ?

    public class AAA {
        protected String someValue;
        
        public static class BBB {
            protected String someValue;
        }
    }

maybe I need to change something in my pojo.mustache and use oneOf property?
