   looking a little bit into this issue you probably need to substitute:
   - `net.minidev.json.JSONValue`
   - `net.minidev.json.JSONWriter`
   
   Something like:
   
   ```java
   @TargetClass(JSONValue.class)
   class JSONValueSubstitution {
       
       @Substitute
        public static void writeJSONString(Object value, Appendable out, 
JSONStyle compression) throws IOException {
                if (value == null) {
                        out.append("null");
                        return;
                }
                Class<?> clz = value.getClass();
                @SuppressWarnings("rawtypes")
                JsonWriterI w = defaultWriter.getWrite(clz);
                if (w == null) {
                        if (clz.isArray())
                                w = JsonWriter.arrayWriter;
                        else {
                                w = 
defaultWriter.getWriterByInterface(value.getClass());
                                if (w == null)
                                        throw new 
UnsupportedOperationException("...")
                        }
                        defaultWriter.registerWriter(w, clz);
                }
                w.writeJSONString(value, out, compression);
        }
   }
   ```
   
   ```java
   @TargetClass(JSONWriter.class)
   class JSONWriterSubstitution {
       @Delete
       static public JsonWriterI<Object> beansWriterASM;
   }
   ```
   
   Not sure it it is enough but the issue is that the library tries to generate 
classes in case it does not find a suitable writer. 
   
   An potential future evolution would be to generate such classes at build 
time.
