Incompatible types for common

I define jackoson serializer and add it to the java class as JsonDeserialize like this:

@JsonDeserialize(using = ReportFilterDeserializer.class)

      

        
        
        
      

    

The compiler reports this error:

error: incompatible types: Class<ReportFilterDeserializer> cannot be converted to Class<? extends JsonDeserializer<?>>
@JsonDeserialize(using = ReportFilterDeserializer.class)

      

        
        
        
      

    

Annotation value:

public Class<? extends JsonDeserializer<?>> using() default JsonDeserializer.None.class;

      

        
        
        
      

    

If I remove the shared attribute from the ReportFilterDeserializer its passed compilation. I don't understand why the complaint is complaining.

class ReportFilterDeserializer<T> extends JsonDeserializer<ReportFilter<T>> {
    @Override
    public ReportFilter<T> deserialize(JsonParser jsonParser,DeserializationContext arg1) throws IOException,JsonProcessingException {
        return null;
    }
}
